Synthesis and properties of ZnO nanoparticles at room temperature: Effect of capping agent
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 8
Abstract
Zinc Oxide nanoparticles in aqueous phase were studied using an easy, cost effective and environmental friendly co-precipitation method. ZnO nanoparticles are of special interest due to its non-toxic nature towards health. This paper reports on structural and optical properties of polymer capped ZnO nanoparticles prepared through wet chemical method using PVP (polyvinylpyrrolidone) as capping agent and acidic level maintained by using NaOH at pH-9. Due to capping agent the dynamic of binding and unbinding and its concentration become prerequisite for reduction of particles size and formation of agglomeration. The XRD analysis confirms the growth of wurtzite phase of ZnO nanoparticles. Scanning electron microscope (SEM), energy dispersive analysis of Xrays (EDAX), photoluminescence (PL) and Fourier transform infrared (FTIR) spectrophotometers were employed to study the structural, morphological, compositional and luminescence properties.
