摘　　要：采用熔融晶化法制备Tm^(3+)‑Tb^(3+)‑Eu^(3+)掺杂含Na_(3)Gd(PO_(4))_(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,Tm_(2)O_(3)、Tb_(4)O_(7)、Eu_(2)O_(3)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(0.3332,0.3188),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Tm^(3+)→Eu^(3+)、Tb^(3+)→Eu^(3+)的能量传递。Tm^(3+)‑Tb^(3+)‑Eu^(3+) co‑doped fluorescence glass ceramics containing Na_(3)Gd(PO_(4))_(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 Tm_(2)O_(3),Tb_(4)O_(7)and Eu_(2)O_(3)were 0.2%,0.2%and 0.95%,respectively,the chromaticity coordinates of glass ceramics were(0.3332,0.3188)close to the standard white light(0.333,0.333).Combined with fluorescence spectra and fluorescence decay curve analysis,the energy transfer of Tm^(3+)→Eu^(3+),Tb^(3+)→Eu^(3+)in the sample was confirmed.
