Abstract:
     A process for in-situ growth of zinc selenide nanocrystals in SiO2 gel glass matrix features that the reagent for gel glass contains ethyl ester of normal acid, absolute alcohol and selenic acid as hydrolyzing catalyst, the Se and Zn sources are introduced in zinc selenate form, after the sol is poured in culture dish and the culture dish is covered by filter paper. It is laid aside for more than 6 weeks to obtain transparent dried gel, and the dried gel is thermally treated by two steps to obtain zinc selenide.
