摘　　要：测量了掺Er3+离子碲酸盐玻璃的吸收光谱和荧光光谱,经荧光光谱测试发现掺Er3+离子碲酸盐玻璃的荧光半高宽可达80 nm,应用McCumber理论计算了1 531 nm处的受激发射截面可达7.5×10-21cm2.对Er3+离子在不同基质玻璃中光谱特性的比较发现,Er3+离子在碲酸盐玻璃中具有相对较高的受激发射截面和宽的荧光半高宽.Jinan City as a key national water- shortage cities, water shortages have become bottleneck factor of sustainable economic and social development of Jinan. Optimal allocation of water resources as an important means of addressing the shortage of urban water resources, its implementation plays an important role in supporting sustainable development throughout the Jinan＇s economy. Jinan City optimal allocation of water resources from the implementation of projects undertaken by means of engineering and non - engineering means, thus ensuring the sustainable use of water resources of Jinan City.
