Er^3 -doped Al2O3 films were deposited on silicon substrates by reactive closed-field unbalanced magnetron sput-tering. The process parameters, such as target bias voltage, substrate bias voltage, O2 gas flows, sputtering gas pressure, were studied. The 1.53μm photoluminescence characteristics from Er^3 were measured. The relations among the PL peak intensity, annealing temperatures, and pump power were experimentally investigated. 相似文献

介绍一种掺铒玻璃样品的制作方法,实验测量了单片及两片掺铒玻璃样品的荧光特性.结果表明:两片掺铒玻璃样品级联的荧光强度比单片掺铒玻璃样品的荧光强度高,半值宽度与高浓度单片样品的半值宽度近似相等;在两片掺铒玻璃样品级联的形式中,浓度高的样品靠近抽运光源时的荧光强度比浓度低的样品靠近抽运光源时的荧光强度高;两种低浓度样品组合的荧光强度相对于其单片样品荧光强度的增幅比两种高浓度样品组合的荧光强度相对于其单片样品荧光强度的增幅要高.

Experimental investigation of photoluminescence spectra of Yb3+ sensitized Er3+-doped glass samples in series 总被引:1,自引:0,他引:1
Fabrication technology of the Yb3+:Er3+ co-doped glass samples is introduced. Photoluminescence (PL)characteristics of a single sample were experimentally investigated. The PL peak intensities of two samples in series were measured and discussed. The results show that the PL peak intensities of two samples in series depend on pump manners and arrangement of the samples. The better amplification ability can be obtained by two samples in series doped with low-concentration ytterbium instead of a single sample doped with high-concentration ytterbium. 相似文献
