Abstract
In this work the temperature role on the evolution of the nanoparticle geometrical shape in CoSe nanoparticle arrays have been investigated. The data showed that temperature can affect the optical band gap, surface morphology and shape but the deposition temperature plays a crucial role in the shape controlling. We present a simple solution processed synthesis route for CoSe nanostructure thin films using chemical bath deposition method. The films were characterized by X-ray diffraction (XRD) for structure characterization, UV-visible spectroscopy for band gap determination, EDAX technique for elemental analysis and scanning electron microscopy (SEM). SEM pictures show nanoparticles shape with temperature.
