Transient photobleaching of trapped electrons
Abstract
Intense light pulses from a ruby laser have been used to saturate trapped electron absorptions in crystals (viz. KBr and KI) and low temperature glasses (viz. aqueous 10 M-OH– and MTHF) and have shown that (i) the electron band is broadened homogeneously in the crystals and heterogeneously in the MTHF glasses, and (ii) the characteristics of transient and permanent photobleaching differ very markedly in each system.
