Abstract
Phosphor compositions for highly reliable white light-emitting diode (LED) devices are disclosed. The phosphor compositions include a first oxynitride-based phosphor that emits green light and a second nitride-based phosphor that emits red light. When the weight ratio of the first oxynitride-based phosphor to the second nitride-based phosphor is from about 8:2 to 9:1, the emission spectra of the phosphor compositions are very similar to that of a yellow YAG phosphor with a peak at 550 nm. The phosphor compositions have emissions with CIE color coordinates satisfying an equation expressed as:
