Structural and Luminescence Properties of ZnO Nanoparticles Synthesized by Mixture of Fuel Approach in Solution Combustion Method

Abstract

Zinc oxide has been used for many applications, for example optoelectronic devices, ceramics, catalysts, pigments, varistors and many other important applications. In this study, ZnO nanoparticles were synthesized by mixture of fuel approach in solution combustion method. Mixtures of urea, glycine and citric acid were mixed at room temperature with Zinc nitrates as fuels resulting in spontaneous ignition resulting in production of ZnO nanopowder. The crystal structure and size of the synthesized powder were determined by X-ray diffractometer (XRD), which revealed that the synthesized ZnO nanopowder has the pure wurtzite structure having crystallite size 26-40 nm. Optical studies of nanomaterial were examined by FTIR and UV-Visible absorption spectrum. The luminescence studies also investigated in the visible region 360-800 nm with excitation 325 nm laser. These nanomaterials may be used in solid-state lightening devices.

Microwave-Assisted Green Synthesis of Pure and Mn-Doped ZnO Nanocomposites: In Vitro Antibacterial Assay and Photodegradation of Methylene Blue

“…XRD patterns show these diffraction peaks at 31.9, 34.5, 36.4, 47.6, 56.8, 62.9, 68.0 position of the 2θ value, and these correspond to their characteristic Bragg peaks of (100), ( 002), ( 101), ( 102), ( 110), ( 103) and (112) (Pathak et al, 2016;Zhan et al, 2021). These characteristic peaks correspond to the hexagonal or wurtzite structure of ZnO NPs and Mn-doped ZnO nanoparticles (Pathak and Swart, 2019) as shown in the JCPDS card no.80-0075. The average crystallite size of the synthesized nanoparticles was calculated by using the Scherrer equation.…”
