“…PVA (aq) and FeCl 3(aq) are combined in a ratio 10:2 and 10:5, at 25 °C, with conventional drying of samples C and F for 24 h at normal laboratory conditions. Starting here, the intramolecular interaction of components [18,19] ], with the production of ferrous chloride (FeCl 2 ), ferrous hydroxide, Fe(OH) 2 , ferric hydroxide, Fe(OH) 3 , hydrogen gas, H 2 , and chlorine gas, Cl 2 , [53,[68][69][70][71][72][73][74][75] this process darkens the sample film. Lastly, the photo-electrochemical process is performed by a redox reaction.…”

Abstract:We show experimentally that the metallic salt, FeCl 3 , at different concentrations, provides photosensitivity and conductivity characteristics with poly(vinyl alcohol) material. The holographic recording in this photosensitive material was made in real time.The effect of applied voltage on holographic diffraction gratings in the recording process and the changes in their diffraction efficiency, depending on their composition, are shown. In addition, we describe the photo-mechanism, physicochemical processes, and water condensations involved in changes of the formation of images due to applied voltage. The results suggest that polymers doped with metallic salts may have potential as inexpensive photosensitive materials that are easy to work under normal laboratory condition.
