Structural, FTIR and photoluminescence studies of Fe doped ZnO nanopowder by co-precipitation method.
K. Raja,P. S. Ramesh,D. Geetha +2 more
TL;DR: An investigation on Fe-doped ZnO nanopowder synthesized by co-precipitated method annealed at 550°C showed a decrease in the energy gap with increasing Fe content, probably due to an increase in the lattice parameters.
Journal ArticleDOI
Studies on visible light photocatalytic and antibacterial activities of nanostructured cobalt doped ZnO thin films prepared by sol-gel spin coating method.
TL;DR: The Co doped ZnO films were found to exhibit improved photocatalytic activity for the degradation of methylene blue dye under visible light in comparison with the undoped ZNO film and the bactericidal efficiency was investigated against a Gram negative and Gram positive bacteria.
