In 1996, a new lighting device was proposed by Nichia Chemical Co., Japan, using a blue InGaN LED chip coated with a yellow-emitting phosphor of yttrium aluminum garnet (Y2.9Ce0.1Al5O12, YAG:Ce3 +), so-called white LEDs. The lighting device has numerous advantages over traditional incandescent and fluorescent lamps in the viewpoints such as small size, long lifetime, robustness, fast switching, and high efficiency. The performances, such as emission efficiency and color rendering index, of the lighting device are known to strongly depend on the luminescence properties of phosphors. Therefore, the aim of this review is to provide answers for questions regarding the kinds of phosphor host materials that should be selected, the kinds of robust structures that should be targeted, which rare earth elements should be selected for the desired color emissions, and how the materials should be synthesized.
