Abstract
Zn2SiO4: Mn2+ thin films were fabricated by spray pyrolysis. FT-IR spectroscopy was applied to study both the chemical reactions in solution during the preparation of spray solutions and pyrolysis of the deposited films. Spray solutions were prepared by two routes: (1) a reaction based on the formation of ZnO nanoclusters from zinc acetate (ZnO cluster route), (2) a reaction based on the hydrolysis of tetraethylsilicate (silicate hydrolysis route). The progress of the reactions in ethanol solution was discussed from the wavenumber difference between two absorption peaks of the carboxylic group of acetic acid from zinc acetate. The pyrolysis process was monitored in-situ by high-temperature IR transmission spectra, which clarified the thermal degradation process of organic contents and the state of amorphous inorganic residues.
