研究了共掺杂(Cr6+，V5+)和(Cr6+，Ag+)离子在10~300K温度范围内的发光和衰减曲线。这些离子的闭壳层电子结构揭示了发光和衰减曲线受能量迁移过程、表面效应和纳米结构基质的制备方法的敏感影响。(C)1998 Elsevier Science B.V.保留所有权利。
Luminescence and decay profiles of codopant (Cr6+, V5+) and (Cr6+, Ag+) ions in sol-gel silica glasses are investigated at temperatures between 10 and 300 K. The closed-shell electronic structures of these ions reveal luminescence and decay profiles affected sensitively by energy migration processes, surface effects and preparation methods of the nano-structured matrices.
