ABSTRACT

Role of NaOH concentration on Structural, Morphological and Optical Properties of ZnO Nanopowders Synthesized by Sol-gel process

A.Vanaja*,G.V.Ramaraju, K.Srinivasa Rao

ABSTRACT

In the Present work, Structural, Morphological, Compositional and optical properties of ZnO Nanopowders synthesized by sol-gel process at different concentrations of NaOH were reported.The synthesized Nanopowders were further analyzed using XRD, SEM, FTIR, UV-Visible optical absorption and PL characterizations. Crystalline size and Lattice strain determined from XRD spectra. Morphology of Nanopowders viewed from SEM images observed at different magnifications. The presence of Functional groups analyzed from FTIR spectra. Optical properties of absorption and emission were resolved using optical absorption and PL characterizations. From the results it was very clear that particles synthesized with different NaOH concentrations played a vital role on Structure, Surface morphology, optical properties of Nanopowders. As synthesized Nanopowders can further utilized in Fabrication of Various optoelectronic devices including solar cells, LED etc Keywords: FTIR ,Nanoparticles,SEM,XRD,Zinc Oxide.
