白光LED用红色荧光粉KLa(MoO4)2∶Eu3+的制备及发光性能
Preparation and Optical Properties of Red Emitting Phosphor KLa (MoO4) 2 ∶ Eu3 + for White LEDs
摘要
Abstract
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.关键词
