Structural and morphological features of sol-gel processed pure and Indium doped ZnO nanoparticles

High purity ZnO nano particles and Indium (In) doped Zinc oxide (ZnO) nano particles were synthesized by simple sol-gel technique at low temperature of 70°C. Different compositions of Indium (In) doped zinc oxide with Zn_1-xIn_xO (x=0.01 to 0.08 atomic percent) were prepared by low cost sol-gel technique. The powders were examined for their structural study using XRD. It has been found from diffraction data that the pure and Indium doped powders have formed to be single phase hexagonal wurtzite crystal structure. The microcstrutured parameters such as strain, lattice constant, particle size, dislocation density, bond lengths between Zn and O were calculated. Using the calculated values of particle size from XRD & SEM crystallinity index was estimated. From the observed crystallinity index data of the prepared nano materials it was confirmed that the materials were showing polycrystalline nature.
