摘要

The solvothermal technique was used to make the iron manganese magnesium tetra-oxide (FeMnMgO4) nanocomposites (NCs). The absorbance spectrum was computed utilising a UV-Visible-NIR spectrophotometer. At 860 nm, the FeMnMgO4 NCs exhibit a broad single absorption peak and it turns out that the smallest cut-off wavelength is 305 nm. Fluorescence (FL) spectra were measured for a nanocomposite at a wavelength of emission is found to be at 466 nm is helpful for LED applications. FTIR analysis was utilized to categorize the functional groups. The existence of a cubic structure is verified for utilising powder X-ray diffraction (PXRD). Vibrational modes are examined via Raman spectroscopy study. TGA method has been utilised to analyze a material’s thermal stability and the synthesized NCs occurs two stages of weight loss. To find out how a chemical breaks down at temperatures above a specific threshold in degrees Celsius, use DSC analysis. The resulting FeMnMgO4 nanocomposites show no melting point at temperatures above 1000 °C. The nanocomposites could melt at temperatures higher than 1000 °C. Using scanning electron microscopy (SEM), the surface morphology was determined and EDAX analysis utilised to verify the elemental form. FeMnMgO4 NCs utilized for XPS examination has been employed to investigate surface characteristics. DSC analysis of FeMnMgO4 NCs is a special material with improved high-temperature performance and it is recommended for LEDs and several optoelectronic devices.
