以磷酸二氢铵、氧化锌、碳酸锶、六水硝酸铈、七氧化四铽和碳酸锰为原料,用熔融-可控析晶法制备了Ce/Tb/Mn共掺的ZnO-SrO-P2O5体系发光玻璃陶瓷材料。采用X射线衍射仪、荧光分光光度计和国际照明委员会(CIE)色度图对其相的组成、光谱学和发光特性进行研究。结果表明:经(500℃,2 h)+(570℃,2 h)热处理后样品主晶相为SrZnP2O7。在波长358 nm的紫外光激发下,在Ce/Tb/Mn共掺杂玻璃陶瓷的发射光谱中同时观测到了蓝光、绿光和红橙光的发射带,这些发射带的混合实现了白光的全色发射显示。此外,Ce/Tb/Mn 三元共掺杂玻璃陶瓷的发光颜色随着Mn2+含量的增加从蓝白光逐渐过渡到白光,实现了发光颜色的调控。制备的玻璃陶瓷材料有望用于白光发光二极管和其他光学仪器。

Ce/Tb/Mn co-doped ZnO-SrO-P2O5 system luminescent glass-ceramic materials were prepared by melting and controlled crystallization method using NH4H2PO4, ZnO, SrCO3, Ce(NO3)3?6H2O, Tb4O7 and MnCO3 as raw materials. The phase composition, spectroscopic characterizations and luminescence properties of the glass-ceramics were investigated by X-ray diffraction diffractometer (XRD), fluorescent spectrometer and International Commission on Illumination (CIE) chromaticity diagram. The results show that the main crystalline phases are SrZnP2O7 for all samples subjected to heat treatment of (500 ℃, 2 h)+(570 ℃, 2 h). Blue, green, and reddish orange emission bands are observed in the photoluminescent spectra of Ce/Tb/Mn co-doped glass-ceramics excited by ultraviolet light with wavelength of 358 nm, and the combination of these three emitting bands allows the realization of white light emitting. Moreover, luminescent color gradually from blue white to white emission is observed in the photoluminescent spectra of Ce/Tb/Mn co-doped glass-ceramics with increasing concentration of Mn2+, which indicates that the tunable luminescent color can be achieved. The as-prepared glass-ceramic materials are promising to be applied to white light-emitting diodes and other optical devices.
