银离子光致还原时间效应的荧光光谱研究

Montoring to the Reduction Process of Ag￣+by Fluorescence Time Effect of Absorbed Rh6G

本文通过观察ＡｇＮＯ３溶液在其光致还原出Ａｇ原子并形成Ａｇ晶体微粒过程中所加入的罗丹明６Ｇ（Ｒｈ６Ｇ）分子荧光强度变化的规律，利用吸附分子的荧光在Ａｇ微粒表面会发生淬灭这一效应，给出了通过观察分子荧光淬灭的时间效应来监测Ａｇ＋的光致还原过程的新方法，并讨论了其相应的机制．

The fluorescent quenching process of Rh6G in AgNO3 solution irradiated with Ar￣+ laser beam has been recorded by OMA. The possibility of examining the emission-induced reduction process of Ag￣+to Ag crystal particles by measuring the time effect of fluorescent quenching on Ag surface was discussed.
