Abstract:
Nanocomposites (NCs) of zirconium, lithium, and barium oxide (ZrO2.Li2O.BaO) are synthesized via sol-gel method. The optical characteristics have been characterized using UV-visible spectroscopy, band-gap energy of 4.57 eV, and the minimum cutoff wavelength of 288 nm. FTIR spectroscopy determines whether specific functional groups are present in the nanocomposite. The planes in the BaO tetragonal phase are shown, together with the peaks of ZrO2 and Li2O from powder XRD. Nanocomposites that excite at 363 nm and emit at 502 nm can be useful for fluorescence analysis. Three notable weight loss levels were evidently shown by the TGA curve. DSC analysis shows that the resulting NCs have no melting temperatures up to 1000°C. The morphology was analyzed via FESEM studies, and EDAX analysis was used to determine the materials' chemical composition. XPS helps identify elemental oxidation states and determine elemental composition. According to what we know, there have not yet been reports of photoacoustic spectroscopy (PAS) tests of ZrO2.Li2O.BaO samples, despite the fact that they are crucial for a variety of heat transfer applications. These results suggest potential for future exploration in LED and thermal energy-storage applications.
