Selenium-loaded zeolite (ZSM-5): II. Photoinduced phenomena
Search this article
Description
Photoinduced phenomena in Se-loaded ZSM-5 single crystals have been studied through electron-spin resonance, optical absorption, and photoluminescence spectroscopy. Marked exposure effects appear at room temperature. Upon illumination of visible light, an electron-spin signal at g [approximate to] 2.00 increases by an order, subgap absorption of 10^3 cm^[-1] appears, and photoluminescence at subgap regions weakens to a half. Timescales of these photoinduced changes including recoveries are not the same, which suggests different origins for the three changes. The spin increase evinces bond scission in single Se chains. © 2009 American Institute of Physics
