Current-voltage characteristics of the In2O3 sensor measured in dry air under different UV irradiation conditions (L1, L2, L3, and L4). (b) Gas sensing properties measured at room temperature for 50 ppm NO under different UV irradiation conditions along with the signal levels. (c,d) Response and recovery times as a function of the UV light intensity.
