Minsk light energy storage luminous powder price

What are the characteristics of persistent luminescence materials?

3.1.1. Luminescence characteristics Persistent luminescence materials absorb various light sources, including sunlight and fluorescence, and convert the accumulated light energy into visible light, which frequently consist of an inorganic matrix (known as host) and activated doping ions (activator).

Why does phosphorescent powder have a higher energy storage capacity?

With an increase in the particle size, the energy storage capacity of phosphorescent powder is stronger, benefiting the afterglow intensity . The molecules that constitute these particles act as energy storage houses during the time that they are in lit environments and then release that energy in dark environments.

Which phosphorescent powder should be used for photoluminescence?

In this regard, medium-sized phosphorescent powders are recommended. On the basis of current studies, 70 ∼ 300 mesh phosphorescent powders are usually selected, and a content of 15 %∼55 % is recommended. External factors. The illuminance of light has a direct impact on the photoluminescence.

What is a luminous level?

Luminance represents the luminous flux density in a specific direction and reflects the intensity of the surface luminescence. In terms of different brightness levels, the level that can be recognized by human eyes is shown in Table 7. The lowest luminance recognized by human eyes is about 0.32 mcd/m 2. Table 7.
