Crystallization and Reduction of Sol-Gel-Derived Zinc Oxide Films by Irradiation with Ultraviolet Lamp
TLDR
In this paper, structural changes in sol-gel films with photo-irradiation were investigated using zinc oxide (ZnO) derived from zinc acetate, and the exposure of the films to an ultraviolet lamp induced hexagonal ZnO crystals in a relatively dense amorphous structure.Abstract:
Structural changes in sol-gel films with photo-irradiation were investigated using zinc oxide (ZnO) derived from zinc acetate. The exposure of the films to an ultraviolet lamp induced hexagonal ZnO crystals in a relatively dense amorphous structure. On the other hand, the formation of zinc metal was found in a porous gel film. The photo-induced crystallization and reduction are ascribed to the electronic excitation in the metastable non-crystalline states.read more

Ultraviolet-reduced reduction and crystallization of indium oxide films
TL;DR: In this paper, structural changes stimulated by ultraviolet (UV) irradiations of sol-gel-derived indium oxide thin films were investigated and the results of x-ray photoelectron spectroscopy revealed that charge transfer from O2− to In3+ was induced by the incoherent and the coherent UV photons.
