| 摘 要： | 用溶胶－凝胶方法合成了掺铒的二氧化硅玻璃。在室温下可产生１．５４μｍ波长的红外荧光。实验结果表明：荧光强度随掺杂浓度的不同而改变，并在０．５Ｗ％的掺杂浓度下出现最大值。当温度从４Ｋ升至３００Ｋ时，荧光强度下降了７４％。 |

| Abstract: | Er-doped sol-gel silica glasses which have room temperature photoluminescence at 1.54 microm and doped concentration of 10(20)/cm(3) have been prepared. The examination results Indicated: (1) PL spectrum has largest intensity at the 0.5W% doped concentration; (2) the intensity of PL decreased 74%, when the temperature raised form 4K to 300K; (3) The Er ion and O ions formed complexes with coordinated numbers of 8 or 9. |
