摘要
氧化硅材料在光通信、半导体光电子器件及照明等领域具有广泛应用,对其光学性能研究进行总结、归纳具有重要意义。氧化硅材料本征E’、2种缺氧型以及各种富氧型光活性缺陷中心在光导纤维及紫外吸收等应用中扮演了很重要的作用,某些具有良好发光性能的缺氧中心及掺杂离子或半导体纳米粒子发光中心的深入研究使氧化硅材料在照明领域具有良好的应用前景。对氧化硅材料各类光活性缺陷中心阴离子配位场的修饰将对这些光活性缺陷中心的光学性能产生显著的影响,并有可能进一步提高其发光性能。
The recent progress in researches on the optical properties of silica widely used in optical communication, semiconductor photoelectron apparatus and lighting field is reviewed. The optically active defect centers of such types as E＇, two kinds of oxygen-deficiency and some kinds of oxygenrichness in silica play an important role in optical communication fiber and UV absorption. The researches on some oxygen-deficient defects and the metal ions doped or implanted semiconductor nanoparticles with fine luminescence properties have made it possible for silica to be used in the lighting field. The negative ions modified anion coordination field may remarkably affect and improve the optical properties of the optically active defects in silica.
