铕离子掺杂的钼酸镉红色荧光粉的合成与光谱性质
Synthesis and Spectral Properties of Eu3+ Doped Cadmium Molybdate Micro/nano Materials
摘要
Abstract
In order to optimize the process conditions for the synthesis of fluorescent powder, in this paper, CdMoO4∶ Eu3 + nanoparticles have been synthesized by precipitation method using Cd ( NO3 ) 2 · 4H2O and Na2MoO4 · 2H2O as raw materials. Three kinds of samples under the 300 ℃ were characterized by the X-ray diffraction ( XRD) , scanning electron microscopy ( SEM ) , fluorescence spectrometer ( PL). XRD analysis results show that the preparation of nanoparticles crystallize in ftetragonal system system of scheelite type. The excitation spectrum of CdMoO4∶ Eu3+ monitoring the emission at 615 nm showed that the excitation spectrum consists of an intense broad band with a maximum at 333 nm and three sharp excitation spectrum, which was ascribed to the transition of 7F0 →5 D1、7F0 →5D2、7F0→5L6The emission spectrum excited by 333 nm xhibits two launch peaks of 615 nm、589 nm, which are related to 5D0→7F1、5D0→7F1 transitions respectively.关键词
