Abstract
A self-luminous CaEuAl3O7 phosphor was synthesized by a high temperature solid-state reaction method. The photoluminescence (PL) properties were investigated to examine its application in the development of white light-emitting diodes (w-LEDs). The red emission was observed from Eu3+ ions in CaEuAl3O7 phosphor. CaEuAl3O7:Eu3+/Eu2+ prepared in a thermal-carbon reducing atmosphere shows good absorption ranging from ultraviolet to a blue region centered at 445 nm. The above results indicate that CaEuAl3O7 is a good candidate as red and blue component for near UV-excited w-LEDs.
