摘要
Eu3+-doped KLa(MoO4)2 phosphor was prepared successfully via the hydrothermal process. And it was characterized by X-ray diffraction (XRD), field emission-scanning electron microscopy (FE-SEM) and photoluminescence (PL), respectively. The experimental results indicate that the pH values of the reaction solution have important effects on the phase structures and the morphologies of the products. A crystallization pH value of 7 was optimal. This phosphor can be effectively excited by 279, 395, 465 nm and emits red light at 617 nm with line spectra. The optical properties suggest that KLa(MoO4)2:Eu3+ is an efficient red-emitting phosphor for white LEDs applications.
