Impact of Zn2+ Doping on the Structural, Morphological and Photodiode Properties of V2O5 Nanorods

In the present study, the effects of Zn 2+ doping on the microstructural, morphological and photodiode response of the V 2 O 5 nanorods have been studied. Pure and Zn 2+ doped V 2 O 5 nanorods were prepared by a simple and cost effective wet chemical solution process. The XRD studies confirmed that the pure and Zn 2+ doped samples exhibit crystalline nature with mixed phases for Zn doping. From the morphology analysis, it is observed that substitution of Zn 2+ into the V 2 O 5 matrix is found to gradually transform the morphology from hexagonal face rods to short rods mixed with the plate like structures. The luminescence features of nanostructures are analyzed using photoluminescence studies. Moreover, the V 2 O 5 /p-Si and ZnV 2 O 5 /p-Si photodiodes parameters were studied under dark and light environments.
