Study on Synthesis and Properties of White Light Ba2MgMoO6∶Eu3+,Li+@g-C3N4 Phosphors
摘要
Abstract
Ba2MgMoO6 phosphor doped with rare earth Eu3+was prepared by sol-gel method,and the influence of different charge compensators on the luminescence intensity of the phosphor was explored.Finally,a series of Ba2MgMoO6∶Eu3+,Li+@g-C3N4 phosphors were prepared by precipitation adsorption reaction.The fluorescent powder was characterized by X-ray powder diffraction,UV diffuse reflection,and fluorescence spectroscopy.Results indicate that under the excitation of 365 nm ultraviolet light,the optimal doping concentration for single doped Eu3+is 5%,and the optimal doping concentrations for Eu3+and Li+co-doping are 5%and 3mol%,respectively.By changing the dosage of g-C3N4,the luminescence of the composite fluorescent powder can achieve a transition from blue light to red light.When the mass ratio of g-C3N4 reaches 8%,the fluorescence color coordinates of Ba2MgMoO6∶Eu3+,Li+@g-C3N4 are(0.30,0.28),which can achieve white light emission of(0.31,0.21),close to the color coordinates of standard white light(0.33,0.33),indicating that this fluorescent powder has potential application prospects in the field of white light-emitting diodes.关键词
