The results indicate that different refractive indexes of germaniumsulfide glass films prepared by different precursor are obtained due to the differences in glass structure.
结果表明：采用不同先驱体制备的溶胶凝胶硫化锗玻璃薄膜其玻璃结构具有差异，并导致薄膜折射率的不同；

Germanium can be concentrated in silicate ore deposit, sulfide ore deposit and coal, and partly in porphyry and carbonate, therefore it has good industrial development future.
