The Impact

In this paper we present an investigation on UV radiation on organic-inorganic blend made from conductive polymer (regio-regular poly(3-hexyltiophene) (rr-P3HT) and zinc oxide (ZnO) nanomaterial, which was used as a sensing layer for chemoresistor structure. The study showed that UV radiation has a significant impact on the dynamics of the response of the sensor being studied, which can be a significant element to improve the operation of such sensors at room temperature.

Abstract ZnO quantum dots sensitized SnO2 porous nanowires were fabricated and designed for UV excitation gas sensor. The ZnO/SnO2 composite (SZQ1%) with the molar proportion of 1:100 exhibits excellent sensing properties to NO2 gas under UV irradiation at 40oC. The humidity stability of SZQ1% was also measured and discussed by DC reversed circuit and complex impedance curves. The gas sensing mechanism is well discussed and illustrated to the ZnO quantum dots sensitized and the increased photo-generated carriers under UV irradiation.
