| Abstract(in English) | Cooper phthalocyanine(CuPc)LB film devices were fabricated and the sensing properties of NO_2 gas were investigated. The CuPc LB films were deposited onto glass substrates or the glasses covered with three monolayers of cadmium arachidate LB films, using two xylene solutions containing 0.1mM and 0.5mM CuPc. The πA isotherms suggested the formation of bi-monolayer at the water surface in the case using 0.5mM solution. The excellent deposition was carried out in the case using the glass substrates covered with the cadmium arachidate LB monolayers, which was supported by the AFM measurement. The currents increased with time by the change of the atmosphere gas from N_2 to NO_2 and vice versa. The response spectra strongly depended on the concentrations of the spreading solution and the substrates. The responses were tentatively estimated to be due to the adsorption of the NO_2 gas molecules on the LB films and the diffusion of NO_2 gas molecules into the films. These results are greatly useful for development of NO_2 gas sensors. |
