Abstract :

Crystalline chalcopyrite semiconductor CuInSe2 nanostructures were prepared using a solvothermal route. Cupric chloride, Indium chloride, and Selenium were used as precursors with Dimethyl Formamideor Benzene as a solvent. The process does not require a post–synthesis selenisation step. Structural, morphological and optical properties of the as–synthesized CuInSe2 nanocrystalswere characterized using powder X–ray diffraction analysis, scanning electron microscopy, UV–Vis absorption spectroscopyand dielectric studies. The results indicate that the as synthesized product is of ordered chalcopyrite tetragonal structure with a bandgapof 1.13eV. The shape obtained varies according to the changes in solvent.
