摘要

采用溶胶-凝胶法制备出掺杂双钙钛矿型Gd_2-2xZnTiO₆∶2xDy³⁺(GZT∶2xDy³⁺)白光荧光粉,并通过扫描电子显微镜、X射线衍射仪、荧光光谱仪对样品的微观形貌、晶体结构及荧光性能进行分析和表征。结果表明:Dy³⁺离子掺入GZT基质,且不影响基质本身的晶体结构,形成单一的双钙钛矿型单斜相。在388nm近紫外光激发下,Dy³⁺掺杂样品在483nm、578nm处展示出极强的蓝光和黄光发射。当掺杂离子Dy³⁺的摩尔浓度x=9%时,其CIE色坐标为(0.3115,0.3515),位于白光区域,和标准白光色坐标(0.330,0.330)较为接近,是一种具有潜在应用价值的单一基质白光LED荧光粉。

Abstract

A series of Gd_2-2xZnTiO₆∶2xDy³⁺(GZT∶2xDy³⁺) white phosphors were synthesized by sol-gel method.The morphology,phase structure and luminescent properties of these phosphors were characterized and analyzed by scanning electron microscopy,X-ray diffraction and fluorescence analyzer.The results revealed that Dy³⁺ ions were successfully doped into GZT matrix without affecting the crystal structure of the matrix itself,obtaining single double perovskite monoclinic phase.Under 388nm near ultraviolet light excitation,the obtained samples doped with Dy³⁺ displayed very strong blue and yellow emission at 483 and 578nm.When the concentration of Dy³⁺ reached to 9%(molar fraction),the CIE color coordinates were (0.3115,0.3515),which was close to the standard white color coordinate (0.330,0.330).Therefore,it indicated that this phosphor was potential single matrix phosphor for white LEDs.
