In the present work, V 2 O 5 thin films were fabricated with both commercial and solution combustion synthesised V 2 O 5 resorting to a single spin coating sol-gel deposition. Structural and morphological properties of V 2 O 5 powder were investigated first, subsequently followed by a detailed investigation of the optical and electrochemical properties of thin films. The film, which was coated from as-synthetised powder onto corning substrate had a transparency of greater than 85% in the visible region for sol-gels exhibited absorption edges at ∼380 nm. The optical band-gap energy was evaluated to be 2.7 eV, while the coloration efficiency of this film was found to be 36.8 cm 2 C −1 . The film thickness range of 100-300 nm was demonstrated in 1-layer. The main properties of the afore discussed thin films provide further encouragement for application in future nanoscale (opto-) electronic devices as they are reproducible, cost-effective, and quick to fabricate.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
