Abstract

The blue phosphor material in trichromatic phosphors for white light emitting diodes (WLED) has a great application prospect. Therefore, the silicate blue luminescent material BaCaSiO4:Eu2+, Gd3+ for WLED was prepared by combustion method. Using urea as combustion agent, the optimum sintering temperature and sintering time of primary sintering and secondary sintering were studied. The main emission peak of the luminescent material is located at 499nm, which was the transition emission peak of 4f6 5d1→4f7 of Eu2+, and the luminescence properties of silicate luminescent material could be enhanced by doping a certain amount of Gd3+. The color of light emitted from the luminescent material was pure blue according to the color coordinates obtained from the emission spectrum
