摘要

Copper-iron-cobalt (CFC) trimetal oxide nanocomposites (NCs) are sophisticated, multipurpose materials that improve optoelectronic performance. CFC NCs were synthesized via the hydrothermal method. In the Powder X-Ray Diffraction (PXRD) measurement, the average crystalline dimension was found to be 25 nm. In Raman analysis, the CFC NCs Raman spectra were detected. A particle size range between 30 and 45 nm was observed by Field Emission Scanning Electron Microscopy (FESEM) analysis. Energy Dispersive Analysis of X-rays (EDAX) analysis revealed the presence of elemental compositions. The Photoacoustic spectroscopy (PAS) studies were examined for the first time reported in this article. The thermal diffusivity value of 0.6279 × 10− 6 m2/s was determined from the PAS investigation. According to thermal diffusivity research, heat transfer rates for thermal energy storage (TES) are significantly improved by metal oxide NCs. Greater thermal diffusivity ensures more effective energy storage by reducing temperature differences during phase shift. The occurrence of functional groups is confirmed through Fourier transform infrared (FTIR) spectroscopy analysis. The elemental composition and oxidation states were determined via X-ray photoelectron spectroscopy (XPS) measurement analysis. The NCs are represented by two peaks in the UV-Visible spectroscopy region that were discovered at wavelength of 429 nm and 806 nm. Based on the Tauc relation, the bandgap of the produced NCs is 2.80 eV, suggesting that it is a semiconductor with a broad bandgap. CFC NCs produce blue-to-green emissions organic light-emitting materials, which are distinguished by fluorescence excitation at 367 nm and emission peaks at approximately 448, 465, and 500 nm.
