Abstract

Paper reports humidity sensing studies of V2O5-ZnO nanomaterial. When sample of V2O5-ZnO annealed at 500°C was exposed to increasing humidity, resistance decreased. Aging over six months was within ±6% for ZnO and ±2% for V2O5-ZnO; hysteresis was within ±6% for both ZnO and V2O5-ZnO sensing elements. Grain size for pure ZnO was 620 nm, and 400 nm for V2O5-ZnO nanomaterial. XRD suggested a distribution of crystallite size. For ZnO- V2O5, distribution in the crystallites size was as wide as 130% compared to only 20% for ZnO. Sensitivity of ZnO- V2O5 nanomaterial was 500% more compared to ZnO sample.
