Abstract
(Ca1−xEux)3Al2O6, a red light-emitting phosphor with the excitation of purple-blue light, was prepared by traditional solid reaction method with reducing atmosphere at 1350°C for 4 h in a tube furnace. CaEuAlO4 emerged as an impurity phase when the content of Eu, x, in (Ca1−xEux)3Al2O6 exceeds 0.03. Furthermore, the content of CaEuAlO4 rises with Eu concentration. A strong excitation band centering at 467 nm and a broad emission band centering at 650 nm have been discovered in this phosphor, making it possible to manufacture a bargain price white light LEDs with high CRI.
