Photoluminescent Pigment luminescence principle
Photoluminescent Pigment is usually divided into two categories: Photoluminescent Pigment with photoelectric energy storage and Photoluminescent Pigment with radioactivity. Photoluminescent Pigment is a fluorescent powder that stores light energy after being irradiated by natural light, fluorescent light, ultraviolet light, etc., and then slowly releases it in the form of fluorescence after the light irradiation is stopped. Therefore, at night or in the dark , can still see the glow, lasting as long as a few hours to a dozen hours. Photoluminescent Pigment with radioactivity is to mix radioactive substances into the phosphor, and use the rays continuously emitted by the radioactive substance to excite the phosphor to emit light. This type of Photoluminescent Pigment has a long luminous time, but because of its toxicity and environmental pollution, its application is relatively short. cautious.
Photoluminescent Pigment Glow In dark pigment
Also known as night lightener,it is a kind of powdery photo-storage luminescent material, which realizes the luminescent function by absorbing various visible light, and can be recycled for many times. The product does not contain radioactive elements and can be used as an additive.
Photoluminescent Pigment powder can be used in a variety of transparent or translucent media, such as plastics, coatings, glazes, inks, glass, chemical fibers, resins, etc., to make luminescent products.

Main technical parameters of Photoluminescent Pigment
Initial brightness: Photoluminescent Pigment under a certain brightness of light (1000LUX), the brightness value of the detection instrument at 0 (generally 3 seconds after the light is extinguished). Generally, the bright Photoluminescent Pigment is around 20000-25000. Due to the rapid decrease of the initial moment, the error of the capture moment has a great influence. Generally, it is more appropriate to use the brightness at one minute. The high-brightness Photoluminescent Pigment is generally above 3500 (med/m2), the medium brightening powder is around 2800, and the general brightening powder is around 2300.
Sustainability: With the change of time, the brightness of Photoluminescent Pigment continues to decrease, and the brightness values at different times are compared to measure the speed of its luminescence decline. Generally, 10 minutes, 30 minutes, and one hour of brightness are used for comparison.
Particle size: Particle size is an important parameter of Photoluminescent Pigment, which has a great influence on the application performance of powder. Generally, the average particle size and particle size distribution are used to describe the particle size characteristics, and the unit is micron (um). These parameters are determined by particle size. measured by the tester. In reality, for convenience, the particle size is described by 'mesh' (the number of meshes per living area). Photoluminescent Pigment is generally divided into -160 mesh, -200 mesh, -250, -300 mesh according to the production process. , -400, -200~+400 mesh, -160~+250 mesh, etc. Generally speaking, for Photoluminescent Pigment of the same quality, the larger the particle size, the better the brightness performance, but the worse the performance; The volume will be reduced and the cost will be reduced.
Body Color: Appearance color of Photoluminescent Pigment powder.
Luminous color: The color of the light emitted by the Photoluminescent Pigment powder.
Photosensitive speed: The length of time it takes for Photoluminescent Pigment powder to absorb to saturation under certain light is described. Short time, fast photosensitive, long time, slow photosensitive; good persistence, slow photosensitive. Zinc sulfide can generally absorb enough light within half a minute, while long-lasting luminous powder generally takes more than 15 minutes.
