★ Material ★– Luminescent materials + polystyrene resin. Each one is approximately 0.3*0.5 cm, 0.025 grams.

★ Easy and convenient★–No power required. Place them under sunlight or light to absorb light, and they will emit light.

★ Long service life ★–Light absorption and emission can be reused, allowing it to operate for many years.

★ Automatically emits light in the dark garden★–Absorbs and stores energy from sunlight or other light sources, then emits light in dark environments. Nightlight stones absorb sufficient sunlight or artificial light during the day to glow at night or in any other dark conditions. If it is not bright enough, please shine light on it again.

★ ★–Made from polystyrene. The craftsmanship is exquisite, polished, and there are no sharp edges.

★ Suitable for indoor and outdoor decoration ★–Used for pathways, edges of flower beds, or as filler in pots; for homes, parks, water features, flower pots, greenways, courtyards, lawns, fish tanks, aquariums, and craft decorations.

Primary raw materials: 

Rare earth long-afterglow night light powder, polystyrene resin

1. Luminescent powder

A high-tech self-luminous product made from a rare earth metal element that activates alkaline earth aluminates and silicates. Its function is to absorb light, store it for later emission, emitting light in dark areas (for more than half an hour) while remaining illuminated in bright areas. It has a strong absorption capacity for short-wave visible light below 450 nanometers; by absorbing various natural or artificial lights, it achieves self-luminescence in the dark. This material can be reused indefinitely. It starts with high brightness, has a gentle emission curve, and a long afterglow duration. The afterglow time and luminance of this long-afterglow nightlight powder are higher than those of traditional zinc sulfide storage light powders. Additionally, it absorbs sunlight and ultraviolet light more quickly and can be recycled.

2. Polystyrene resin

Polystyrene (abbreviated as PS) is a polymer synthesized through free radical polymerization of styrene monomers. It is a colorless and transparent thermoplastic that is corrosion-resistant and durable. Being colorless and transparent, it can be freely colored. It has excellent thermal stability and fluidity during melting, making it easy to process into various shapes, especially suitable for mass production. The shrinkage rate during molding is low, and the finished product maintains good dimensional stability. It also has stable chemical properties. Its molecular structure does not absorb water, providing superior resistance to moisture and humidity. It is widely used in the optical industry. It offers good light transmittance, allowing it to be used in manufacturing optical glass and optical instruments, as well as in producing transparent or brightly colored items such as lampshades and lighting fixtures. Additionally, during production, no wastewater is generated, and the solid by-products can be recycled and reused. It is a high-quality, environmentally friendly product.

Answer Sheet on Luminescent Stones: Common Questions

1. Question: Why does luminescent stone glow?
Answer: Luminescent stones are made of luminescent materials and resin. They absorb energy from light and emit light in the dark. Also known as photoluminescent stones, these stones do not emit light on their own; they only glow after absorbing light! The glow is not noticeable during the day or in bright conditions, and it becomes visible only in relatively dark environments. By absorbing light, they also emit light. Over time, the luminescence fades gradually. Luminescence is temporary, but it can be reused by repeatedly absorbing and emitting light.

2. Question: How can phosphorescent stones glow?
Answer: No power is required. It is a light-storing product that emits light by absorbing stored light sources. The nightlight stone does not emit light when received in the delivery package because there is no light source to absorb within the packaging. Simply exposing it to sunlight or light for 5–10 minutes will cause it to emit light again.

3. Question: What can luminescent stones be used for?
Answer: Use them on walkways, edges of flower beds, or fill flower pots and fish tanks with luminescent stones to make your garden or patio unique and cool! They are also suitable for household decorations, art and crafts, DIY gifts, night lights, etc.

5. Question: Does the night light stone, which has been exposed to sunlight all day, still not glow at night?

Answer: Luminescent stones emit light by absorbing light sources, then absorb more light and emit again. They also begin to glow during the process of storing light. If the stone absorbs light during the day and there is no light source to absorb it after the high-luminosity period of the luminescence, only a slightly weaker light will be visible. However, when the light is turned on and the stone is illuminated, and then the light is turned off, a very bright luminescence can be seen.

6. Question: Are there luminescent stones that glow for a long time and with high brightness?

Answer: Energy neither arises from nothing nor disappears from nothing. It can only be transferred from one object to another, and the form of energy can also be converted between them.Law of Conservation of Energy. The same is true for luminescent stones; as long as there is continuous light absorption, they will continue to emit light. However, at night or in dark places, without light absorption, the stored light will gradually deplete, resulting in very bright, brightly lit, moderately bright, faintly lit, or no light at all…… until light absorption occurs and they emit light again. The decay of the luminescence (afterglow) consists of two stages: rapid decay at the beginning and slow decay later on. The duration of the luminescence (afterglow) depends on the amount of stored energy (light energy) and the absorbed energy.

The luminescent stone does not produce a noticeable glow during the day or in bright conditions; its luminescent effect is only visible in relatively dark environments! Our luminescent material is environmentally friendly and can emit fluorescence (like firefly light) in the dark—it is not comparable to electrical lighting materials! Do not mistakenly assume that luminescence can compare with light sources.

7. Question: What is the difference between your luminescent stone and others'?

Answer: We areHigh-brightness night light, the difference lies inLuminous TimeandLuminescent BrightnessJust compare it against lower prices, and you’ll understand. The fear isn’t in comparing goods, but in not knowing what to look for. Compare quality at the same price, or price at the same quality.
