Title
Behavioral features of photostimulated processes in the heterogeneous composition of polymer–semiconductor–salt of a metal
Abstract

In the current study experimental data about changes in the photosensitive composition consisting of polyvinyl alcohol, zinc oxide and bismuth chloride (PVA–ZnO–BiCl3) under UV-irradiation are presented. There are both organic (PVA) and inorganic compounds of the named composition whose changes are determined. The main products of the photostimulated reactions are metal bismuth, bismuth oxide and polyene structures of various lengths in the form of a polyvinyl alcohol. In this research a heuristic scheme of photostimulated reactions in the photosensitive composition of PVA–ZnO–BiCl3 and in similar compositions was suggested.

► The synchronous organic–inorganic modification in photosensitive composition is shown. ► The apparent image on the photocomposition is formed by Bi, Bi2O3 and –CC–CC– formation. ► The heuristic mechanism of photostimulated processes in PVA–ZnO–BiCl3 was offered. ► Using PVA–ZnO–BiCl3 as an example, the energy transfer process can be studied.
