Tungstate Makes LED Colorful
Tungstate is the most classic one of the inorganic luminescent materials, as early as in 1896, scientists found that CaWO 4 can be applied to X-ray emission. In 1906 for the first time to be used as X phosphor materials, tungstate materials quickly penetrate into all aspects of human life. In 1948, people found that the brightness of tungstate with compound purity increases, tungstate can be launched by some elements, these rare earth elements doped tungstate lattice, can make it shine with special properties. In recent years, the energy-saving lighting industry has developed vigorously. However, the efficient lighting products are unable to avoid the mercury pollution problems while saving electricity and reducing energy consumption, with the developing of tungstate phosphors, LED has gradually become the market mainstream. Tungstate phosphors are those that can absorb energy (the absorbed energy including electromagnetic wave (including visible light, ultravi...
