3 and –C
C–C
C– formation. ► The heuristic mechanism of photostimulated processes in PVA–ZnO–BiCl
3 was offered. ► Using PVA–ZnO–BiCl
3 as an example, the energy transfer process can be studied.
In the current study experimental data about changes in the photosensitive composition consisting of polyvinyl alcohol, zinc oxide and bismuth chloride (PVA–ZnO–BiCl
3) 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–BiCl
3 and in similar compositions was suggested.
