Synthesis and Characterizations of ZnO Nanoparticles

Abstract

The ZnO nanoparticles were prepared by two different methods where the size of the particles formed were found to be 320 nm and 559 nm studied by the particle size analyzer. The XRD patterns of these sample revealed that the required phase is present with a little amount of impurities. The particle size measurement which was done by particle analyzer was supported by the XRD Scherer’s formula. SEM micrographs of ZnO-1 sample showed that agglomeration has been taken place where as in ZnO-2 sample showed no more agglomeration. EDX of the ZnO-1 sample confirmed the presence of both Zn and O. DSC analysis of the ZnO-1 sample ensured that there are two endothermic reactions have been taken place at temperature 1350 C and 1650 C but for ZnO-2 sample only one peak was found at 1500 C which reveals that only one endothermic reaction has been taken place. Again TGA analysis of the samples showed significant weight loss of about 5% and 10% at 1350 C and 1650 C temperature respectively in case of ZnO-1 but the weight loss of about 10% has been found at 1500 C temperature in case of ZnO-2 sample.
