The optical and electrical properties of vanadium pentoxide films simply prepared by direct deposition from stable ethanol suspensions of V 2O5 nanoparticles, are found to change after exposure to ammonia. Aimed at developing solid state ammonia sensors able to work at room temperature, spectrophotometric investigations and electrical measurements are performed on vanadium pentoxide films deposited on glass, on V2O 5 films deposited on flexible substrates, having nanosilver electrodes applied on the top, and on n-Si/V2O5 heterojunctions

Abstract
The optical and electrical properties of vanadium pentoxide films simply prepared by direct deposition from stable ethanol suspensions of V 2O5 nanoparticles, are found to change after exposure to ammonia. Aimed at developing solid state ammonia sensors able to work at room temperature, spectrophotometric investigations and electrical measurements are performed on vanadium pentoxide films deposited on glass, on V2O 5 films deposited on flexible substrates, having nanosilver electrodes applied on the top, and on n-Si/V2O5 heterojunctionsFile in questo prodotto:
