摘要：

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.
