Structural and optical properties of V2O5 nanostructures grown by thermal decomposition technique
Source abstract
Abstract
Vanadium pentoxide (V2O5) is a widely used industrial catalyst and a promising substitute to the acidic and hygroscopic PEDOT: PSS hole transport layer in organic solar cells. In this work, V2O5 nanostructures were synthesized by thermal decomposition of ammonium metavanadate (NH4VO3) at various temperatures. Structural and morphological studies confirmed the formation of orthorhombic structure of V2O5 nanorods. The UV–Vis–NIR reflectance spectra show a temperature dependent red-shift in band gap corresponding to indirect optical transitions. The peaks corresponding to band edge emissions were obtained from photoluminescence spectra. From Fourier-transform infrared (FTIR) studies, the vibrational modes involved in V2O5 nanostructures were identified. Temperature dependence of the precursor NH4VO3 was evaluated from thermogravimetric–differential (TGA/DTA) curves.
