Abstract

Background/Objectives: The synthesis process of Vanadium Pentoxide (V2O5) with organic dyes like acid blue and acid yellow molecules was carried out utilizing the simple precipitation procedure with distilled water as the solvent. To understand more about the composition of the materials, the required characteristics were done on the synthesized samples. Methods: Initially, Powder X-ray diffraction (PXRD) investigation was done on the samples to analyze their amorphous nature. The Images from the Scanning Electron Microscope (SEM) revealed that the synthesized samples have a micro-rod-like structure. The occurrence of functional groups in both synthesized molecules was analyzed using a Fourier-Transform Infrared Spectroscopy (FTIR) study. Findings: The study revealed the presence of a peak at 3408 cm-1, which is caused by stretching vibrations in the N-H group, a peak at 2853 cm-1, which is characteristic of CH3, a peak at 1630cm-1, which relates to the presence of the group-N = N, and a peak at 1040 cm-1, which is characteristic of the C-N group. Additionally, to verify the dielectric nature of the synthesized powder samples, their cut-off wavelength, 245 nm for V2O5 with acid blue dye, and 363 nm for V2O5 with acid yellow dye, can be seen in the UV-vis-NIR absorption spectra. The photoluminescence spectrum displayed red light at Eg=1.7 eV for V2O5 with acid blue molecule and at Eg=1.6 eV for V2O5 with acid yellow molecule. Novelty: The novelty of this study is to test the suitability of V2O5 molecules with acid blue and V2O5 molecules with acid yellow as the best materials for utilization in optoelectronic devices, which is not addressed in existing studies.
