采用固相法制备了钽酸钇（YTaO4）、铌钽酸钇（YTaNbO4）、铌酸钇（YNbO4）、铕铽激活钽酸钇（YTaO4:Eu、YTaO4:Tb）和铕激活铌酸钇（YNbO4:Eu）荧光粉。反应，由 Y2O3、Eu2O3、Tb4O7、Ta2O5、Nb2O5 和 Na2SO4 组成的均匀混合物作为助熔剂。报道了钽酸钇基荧光粉的光致发光 (PL)、热受激发光 (TSL)、X 射线衍射 (XRD) 和扫描电子显微镜 (SEM)。在本研究中，首先研究并报告了暴露于 β、UV（311 nm）和 X 射线辐射后这些磷光体的 TSL 特性。 (C) 2011 Elsevier B.V. 保留所有权利。
Yttrium tantalate (YTaO4), yttrium niobium-tantalate (YTaNbO4), yttrium niobate (YNbO4), europium and terbium activated yttrium tantalate (YTaO4:Eu, YTaO4:Tb) and europium activated yttrium niobate (YNbO4:Eu) phosphors were prepared by solid-state reaction, from a homogeneous mixture consisting of Y2O3, Eu2O3, Tb4O7, Ta2O5, Nb2O5 and Na2SO4 as flux. Photoluminescence (PL), thermally stimulated luminescence (TSL), X-ray diffraction (XRD) and scanning electron microscopy (SEM) of yttrium tantalate based phosphors are reported. In the present study TSL characteristics of these phosphors were first investigated and reported after exposure to beta, UV (311 nm) and X-ray radiations. (C) 2011 Elsevier B.V. All rights reserved.
