Cathodoluminescence emission study of nanostructured SnO2 films deposited by spray pyrolysis

In this paper the results of cathodoluminescence (CL) emission study of undoped and doped SnO films are discussed. SnO films were deposited by spray pyrolysis method. It was shown that the study of CL emission is effective method for structural characterization of metal oxides aimed to gas sen...
