Green light activated hydrogen sensing of nanocrystalline composite ZnO-In(2)O(3) films at room temperature

The possibility of reducing the operating temperature of H(2) gas sensor based on ZnO-In(2)O(3) down to room temperature under green illumination is shown. It is found that sensitivity of ZnO-In(2)O(3) composite to H(2) nonmonotonically depends on the oxides’ content. The optimal ratio between the c...

description The possibility of reducing the operating temperature of H(2) gas sensor based on ZnO-In(2)O(3) down to room temperature under green illumination is shown. It is found that sensitivity of ZnO-In(2)O(3) composite to H(2) nonmonotonically depends on the oxides’ content. The optimal ratio between the components is chosen. The new mechanism of nanocrystalline ZnO-In(2)O(3) sensor sensitivity to H(2) under illumination by green light is proposed. The mechanism considers the illumination turns the composite into nonequilibrium state and the photoconductivity change in the H(2) atmosphere is linked with alteration of nonequilibrium charge carriers recombination rate.
