The effect of anneal temperature on physical properties of SnS films
چکیده انگلیسی

SnS thin films were deposited on ITO substrates from SnCl2 and Na2S2O3 aqueous solution by pulse electro-deposition method, and the as-prepared SnS thin films were annealed at different temperatures in air for 1 h. The XRD pattern shows that the film decomposed and was oxidized completely at 250 °C. The surface morphology and grain size changed with the annealing temperature. The increase of the annealing temperature improved the crystallinity of the deposit and made the scope of absorbed light wavelength larger. Also, the direct energy gap Eg changed with the annealing temperature. The SnS thin films annealed at 100 °C have good crystallinity and show strong blue-UV emission, being promising for applications in optical devices. And the band-to-band emission peak (∼920 nm) of the SnS thin film indicated the energy gap is 1.37 eV.
