利用光纤传输测量拉曼光谱的研究

采用多模熔石英光纤对磷酸铕玻璃和铒的磷酸盐烧结体样品进行了光纤传输拉曼光谱测量，并与直接测量样品的拉曼光谱进行对比，两者的结果基本符合，从而证实了光纤传输拉曼光谱对样品检测的可行性，达到扩展拉曼光谱仪的应用领域，为特定条件下研究材料性能提供了良好的途径。由此还可发现和研制出新的光电产品材料。     

Direct Sensitization Up-conversion Mechanism in Er3+∶Yb3+ Co-doped Fluoride Materials

Up-conversion luminescence have been studied on Yb3+-Er3+ co-doped fluoride samples. Two infrared lasers with wavelength of 930 nm and 858 nm are carefully chosen as excitation sources. The experimental results suggest direct cooperation sensitization up-conversion rather than two-step sensitization up-conversion is responsible for the increased population of 2H11/2 (Er3+) and thus the increased green emission in the region 514～574 nm in Yb3+-Er3+ co-doped system.
