摘要

采用溶胶-凝胶法制备出了YVO4∶Eu3+荧光粉,在高温下对YVO4∶Eu3+荧光粉进行退火处理以改善其发光性能。采用X射线衍射仪、扫描电子显微镜和荧光分光光度计对YVO4∶Eu3+荧光粉的微观结构和发光性能进行表征和测试。结果表明:退火后的YVO4∶Eu3+荧光粉具有明亮的红光发射,将高性能的YVO4∶Eu3+荧光粉应用于手印显现技术中,可实现潜在手印的显现,且清晰度高。

Abstract

YVO4∶Eu3+ phosphor was prepared by sol-gel method,and the YVO4∶Eu3+ phosphor was annealed at high temperature to improve its luminescence performance.X-ray diffractometer,scanning electron microscope and fluorescence spectrophotometer were used to characterize and test the microstructure and luminescence properties of YVO4∶Eu3+ phosphor.The experiments showed that YVO4∶Eu3+ phosphor after annealing had bright red-light emissions.The high-performance YVO4∶Eu3+ phosphor was applied to the display technology of fingerprints,which enabled to realize the display of potential fingerprints with high definition.
