Evaluating the moisture resistance of Y3Al5O12
Ce3+ phosphor used in high power white LED packaging
Owing to its low cost and high efficiency, the blue light-emitting diode (LED) chip covered with the Y3Al5O12:Ce3+ (YAG) phosphor has become a mainstream technology of high power white LED packaging. However, phosphors are often susc ...
The emission spectra of high color rendering phosphors, mixed with the yttrium aluminium garnet, silicon based oxynitride and nitride based phosphors, were predicted by the Lambert-Beer theory and back propagation neural network (BP NN). Firstly, the modified Lambert-Beer mode ...
At present, most high-power white Light-emitting diode and laser diode (LED&LD) package is usually constructed by a blue LED&LD chip with a Cerium doped Yttrium Aluminum Garnet (YAG:Ce3+) yellow phosphor, but its color rendering performance is severely chall ...
