Phosphor - an overview ScienceDirect Topics
WebZinc sulfide and cadmium sulfide phosphors are especially efficient in electroluminescence. Sulfide-type phosphors are produced from pure zinc or cadmium sulfide or their mixtures by heating them together with small quantities (0.1–0.001 percent) of copper, silver, gallium, or other salts (activators) and with about 2 percent of sodium or ... Web16.1.3.2 Phosphor materials used in LED for general lighting. The requirements of general lighting phosphors are similar to those of fluorescent lamps—in terms of the wavelength of excitation (440-480 nm) and the temperature and moisture stability requirements. The particle size is adjusted to optimize the scattering of the light in the device and to reduce … http://www.dictall.com/indu/001/00036347085.htm birthday wish for my granddaughter
