Sialon phosphors are power luminescent materials composed mainly of familiar elements Si-Al-O-N. These brand-new materials discovered at the beginning of the 21st century are already used commonly for general lighting and high quality full color display. Here, some commercially available phosphors are introduced at the beginning, focusing on green β sialon which has both industrial importance and academic interest. Moreover, forthcoming phosphors applicable for high color rendering lighting or Super Hi-Vision (8K) TV are summarized and typical spectrum control methods are explained using JEM blue phosphor. The contribution of sialon as industrial standard material for optical characterization of power phosphors is also referred finally.
