We developed a Eu2+-doped red-emitting Sr-containing sialon phosphor Sr2Si7Al3ON13:Eu2+ that could play a very important role in high color rendering of white light-emitting diodes (LEDs) for solid-state lighting. It realizes both high efficiency and small thermal quenching under excitation by blue light, which are essential for operation in a high-temperature atmosphere. It shows a highly efficient red luminescence whose external quantum efficiency reaches 73% for 450 nm excitation. These features show that this red-emitting phosphor has high potential for application to white LEDs.
