【摘要】 采用熔融晶化法制备Tm³⁺-Tb³⁺-Eu³⁺掺杂含Na₃Gd（PO₄）₂晶相荧光玻璃陶瓷,并对其光学性能进行了研究。利用差示扫描量热分析（DSC）、X射线衍射（XRD）、扫描电子显微镜（SEM）等测试,确定了样品的晶相结构和最佳热处理条件（740℃/3 h）。在359 nm激发下,Tm₂O₃、Tb₄O₇、Eu₂O₃掺杂浓度（物质的量分数）分别为0.2%、0.2%、0.95%时,玻璃陶瓷的色度坐标为（0.333 2,0.318 8）,接近标准白光（0.333,0.333）。结合荧光光谱和荧光衰减曲线分析,证实了样品中存在Tm³⁺→Eu³⁺、Tb³⁺→Eu³⁺的能量传递。更多还原

【Abstract】 Tm³⁺-Tb³⁺-Eu³⁺ co-doped fluorescence glass ceramics containing Na₃Gd（PO₄）₂ crystals were synthesized by melt crystallization method and luminescence properties were studied.The crystal structure and optimum heat treatment conditions（740 ℃/3 h） were determined by differential scanning calorimetry（DSC）,X-ray diffraction（XRD） and scanning electron microscope（SEM）.Under the excitation of 359 nm,when the doping concentrations（molar fraction） of Tm₂O₃,Tb407 and Eu₂O₃ were 0.2%,0.2% and 0.95%,respectively,the chromaticity coordinates of glass ceramics were（0.333 2,0.318 8） close to the standard white light（0.333,0.333）.Combined with fluorescence spectra and fluorescence decay curve analysis,the energy transfer of Tm³⁺→Eu³⁺,Tb³⁺→Eu³⁺ in the sample was confirmed.更多还原
