The principle and application of glow-in-the-dark pigments

July 27th, 2020

Glow-in-the-dark pigments is an inorganic material that automatically emits light in the dark. The luminous powder first absorbs various light and heat, converts it into light energy for storage, and then automatically emits light in the dark, and realizes the luminescence function by absorbing various visible light. The following short-wave visible light, sunlight, and ultraviolet light (UV light) have strong absorptivity.
Glow-in-the-dark pigments is a kind of luminous substance with special crystal structure. It has strong light absorption-storage-luminescence ability. When illuminated by natural light and lighting, it absorbs and stores part of the light energy, and in the dark, it will be visible in the form of light. Release slowly. After 5 minutes of illumination, the luminescent material can automatically emit light for more than 5 hours in the dark. The process of absorbing and emitting light can be repeated countless times, and the luminous life is more than 10 years.

Features of glow-in-the-dark pigments:

1. The glow-in-the-dark pigments does not need power supply, can automatically absorb any light source, and automatically emit light in the dark;
2. The glow-in-the-dark pigments has good light resistance, aging resistance and chemical stability, and has a service life of more than 15 years;
3. Luminous powder is currently the most complete product of luminescent pigments, such as yellow-green, blue-green, special sky blue, white, green, pink, pink, orange, orange, yellow, purple, etc.;
4. The noctilucent powder is non-toxic, non-radiative and non-flammable and explosive, and is a new generation of green and environmentally friendly luminescent materials.
5. High brightness and long time (absorb light for 5-20 minutes under sunlight or light irradiation, and the effective continuous lighting reaches 6-15 hours);
6. It is easy to get wet and agglomerate, which will affect the processing process, but does not affect the luminous effect;
7. The finer the powder particles, the weaker the brightness and the shorter the luminous time.

Scope of application of glow-in-the-dark pigments

The luminous powder has strong light absorption, light storage and luminescence ability, and can be used in an infinite number of cycles. After absorbing visible light for 20 minutes, it can last for about 12 hours in the dark. It can be added to plastics, paints and ceramic glazes to make luminous signs, luminous glass, luminous ceramics, special luminous work clothes, and can also be used to display night objects, clocks, telephone buttons, buttons, field instruments, indicators, radios, cameras, Cinema seat numbers, traffic signs, clothing printing, power switches, fishing equipment, building decoration, identification of fire emergency escape systems, military equipment, transportation tools, etc. luminous products. It has a good indication effect and beautification effect in the dark place.
