摘要
采用溶胶-凝胶法制备Er∶YbGG纳米粉体,利用XRD、TG-DTA、IR和SEM等测试手段分析了Er∶YbGG纳米粉体的物相结构和光谱性能。结果表明:Er∶YbGG纳米粉体属于立方晶系,空间群为Ia-3d,晶格参数a=1.216 2 nm。在980 nm激光激发下,Er∶YbGG纳米粉体在1 533 nm附近获得了较强的发射,其较高的发射强度得益于Yb3+-Er3+离子之间的能量传递。
Er∶ YbGG nanopowder was prepared by sol-gel method.XRD,TG-DTA,SEM and spectra analysis were utilized to investigate the phase structure and spectrum properties of the powder.The experiment results indicate that the fine Er∶ YbGG nanopowder belongs to a cubic phase with a space group of Ia-3d and lattice parameter a = 1.216 2 nm.Under 980 nm excitation,an intensive fluorescence emission peak appears near 1 533 nm in the emission spetrum of Er∶ YbGG nanopowder,and the high intensity of the emission is attributed to the energy transmission between Yb3 +and Er3 +ions.
