摘要

Sol-gel method was used to synthesis of zirconium lithium cobalt trioxide (ZrLi2CoO3) nanocomposites initially stated in this article. UV-Vis-NIR studies used to find-out the absorption of the nanocomposites (NCs) at about 290 nm and the band gap energy is found to be 4.12 eV. FTIR analysis was used to identify the functional groups and powder X-ray diffraction analysis utilized to know the nature of NCs. The surface morphology is identified by using a scanning electron microscope (SEM). SEM analysis result exhibits a spherical form, an approximate particle size of 68 nm and the presenting elements were recognized through EDAX analysis. Fluorescence (FL) analysis detects the wide emission band that displays the blue-green emission at ambient temperature. A wideband gap and short wavelength FL emission can be used in LED. The electronic states and chemical environment of the Zr, Li, Co, and O atoms in ZrLi2CoO3 NCs, core-level spectra of X-ray photoelectron spectroscopy (XPS). The thermal stability, material decomposition and other thermal characteristics are find-out by utilising a Thermo-gravimetric analysis (TGA) and Differential Scanning Calorimetry (DSC) analysis. The resulting NCs show no melting point up to 1000 °C and are widely utilized to power modern electronic gadgets such as computers, cell phones, and video cameras.
