Cerium dioxide thin films using spin coating

Cerium dioxide (CeO2) thin films with varying Ce concentrations (0.1 to 0.9 M, metal basis) were deposited on soda-lime-silica glass substrates using spin coating. It was found that all films exhibited the cubic fluorite structure after annealing at 500°C for 5 h. The laser Raman microspectroscopy a...
