Abstract:	Nanostructured cobalt selenide (CoSe2) thin films were deposited on a glass substrate using the selenization of Co films at different selenization temperatures (300°C, 400°C, and 500°C) in a pure Se vapor for two hours. The morphology and structure of the as-deposited films shows that the film morphology and crystallinity are affected by the selenization temperature. Increasing the selenization temperature from 300°C to 400°C and 500°C results in a change in the surface and cross sectional morphology. At 300°C, the Co films have an almost amorphous structure, while at temperatures of 400 and 500°C, the Co films have a crystalline nanostructure with bilayered morphology. Optical analyses of the CoSe2 films at 500°C show a large absorption (α > 1.0 × 105 cm-1) and a direct band gap (∼1.0 eV). © 2015 WILEY-VCH Verlag GmbH & Co. KGaA.
