Theoretical and Experimental Chemistry Aims and scope

Abstract

Rapid processes, which occur on photoexcitation of fluorescein and a series of its halogen derivatives in the presence of ZnO nanoparticles in isopropanol, have been studied by pulse photolysis. The short-lived intermediates have been identified and the kinetics of their destruction have been studied. It is shown that photoinduced transfer of an electron from the singlet and triplet excited molecules of the dyestuffs into the conduction zone of the semiconductor occurs in the presence of ZnO nanoparticles.
