Abstract

Un-doped and Ca-doped EuxVO4and Lal-xEuxVO4vanadate nanoparticles were synthesized by sol-gel method. Phase compositions, morphology and luminescent characteristics of the samples were investigated. The Ca-doping influences on structure of luminescence spectra and chromaticity characteristics of all the samples even at low concentrations. The structure of Ca-related light absorption and emission centers is discussed using results about crystal structure and morphology of the samples.

Ca2+杂质对EuxVO4和La1-xEuxVO4纳米粒子结构、形貌和光学特性的影响

采用溶胶-凝胶法制备了未掺杂和掺钙的钒酸euxvo4和lal - xeuxvo4钒酸盐纳米颗粒。研究了样品的相组成、形貌和发光特性。即使在低浓度下，ca的掺杂也会影响样品的发光光谱结构和色度特性。利用样品的晶体结构和形貌分析结果，讨论了ca相关光吸收中心和发射中心的结构。
