Brightness and luminous powder luminous powder particle size has a direct relationship, luminous larger particles, the brighter the glow, luminous particles smaller glass phosphors glow darker, so luminous, when ye choose What used to see their industry, there is no large particle size requirement, if not the best choice a little rough so luminous luminous effect is more pronounced. The particle size of several relative luminous tile on a black board or on the desktop (this test is best in either the test chamber at night). On the next day close illumination light (preferably purple) phosphor about 10 seconds, then turn out the light producing phosphor brightness comparison, look at the light-absorbing effect fast orange phosphor, obviously, a good light absorption rate than ordinary luminous The luminous powder to be fast, light-absorbing effect is obvious, fluorescent under visible light, the color is white or nearly transparent, light sources at different wavelengths (254nm, 365nm, 850nm) show one or more fluorescent color, Epica phosphor comprising organic, inorganic, twilight and other special effects, colorful and bright. UV phosphors product color variety There are red, purple, yellow and green, blue, green, yellow, white, blue, green, orange, black. A variety of colors, endless variations, UV phosphor.
