- Abstract
This research seeks to fabricate neoteric VSbO4 sheets at various thicknesses (138, 217, 291, and 374 nm) utilizing spray pyrolysis. Scanning electron microscopy was used to analyze the VSbO4 sheets' surface properties. Aside from that, X-ray diffraction demonstrated that all neoteric VSbO4 films revealed a polycrystalline nature with a tetragonal structure. The optical characteristics of the neoteric VSbO4 sheets were investigated using transmission and reflection spectrophotometric readings. The refractive index of the neoteric VSbO4 sheets increased by enlarging the sample thickness. The VSbO4 sheets' Urbach energy magnitudes have increased from 0.113 to 0.146 eV by increasing layer thickness from 138 to −374 nm. Also decreasing from 3.81 to 3.37 eV is the optical band-gap energy. Further, the impacts of layer thickness on the linear optical parameters increase the refractive index, electrical conductivity, real and imaginary sections of the dielectric indices, and optical conductivity. The nonlinear optical indices of the neoteric VSbO4 films grew as the sheet thickness increased from 138 to 374 nm. Further, the activation energy of the explored VSbO4 sheets decreased by increasing the sheet thickness.
