摘要: 采用高温熔融法制备Eu3+-Tb3+共掺杂SiO2-B2O3-Na2O-Y2O3-P2O5前驱体玻璃。对前驱体玻璃粉末进行差示扫描量热(DSC)分析,确定玻璃陶瓷样品的热处理温度。前驱体玻璃热处理后,采用X射线衍射(XRD)和扫描电镜(SEM)分析可知前驱体玻璃中有Na3.6Y1.8(PO4)3晶粒析出。利用荧光光谱对玻璃陶瓷样品的发光性能进行表征,同时分析了Tb3+离子的荧光衰减曲线,确定Eu3+、Tb3+离子的发光机理以及能量传递过程。通过对Eu3+-Tb3+共掺杂玻璃陶瓷样品的发射光谱采集并用色坐标软件和色温计算程序,获得玻璃陶瓷样品的色坐标和相关色温。 |

Abstract: Eu3+-Tb3+ co-doped SiO2-B2O3-Na2O-Y2O3-P2O5 precursor glasses were prepared by high temperature melting method. Differential scanning calorimetry (DSC) analysis of precursor glasses powder was carried out to determine the heat treatment temperature of glass ceramic samples. X-ray diffraction (XRD) and scanning electron microscope (SEM) results showed that Na3.6Y1.8(PO4)3 grains precipitated in the precursor glass after heat treatment. The luminescence properties of glass ceramics were characterized by fluorescence spectra. The fluorescence decay curves of Tb3+ ions were analyzed to determine the luminescence mechanism and energy transfer process of Eu3+ and Tb3+ ions. By collecting the emission spectra of Eu3+-Tb3+ co-doped glass ceramic samples, the chromatic coordinates and correlated color temperatures of glass ceramics samples were obtained by using color coordinate software and color temperature calculation program. |
