Investigation of size-dependent optical and morphological properties of nanocrystalline ZnSe films

Thinfilms of zinc selenide nanostructures (Q-ZnSe) have been grown using an aqueous synthesis route. The as-deposited films investigated using optical absorption and photoluminescence spectroscopy, X-ray diffraction and atomic force microscopy (AFM) exhibits size-dependent properties. Intense photoluminescence in the UV-blue region has been observed in the Q-ZnSe films. AFM analysis revealed that the as-deposited Q-ZnSe films exhibits tendency for self-organization.
