A Study on the NO2 Gas Detection Chracteristics of the Octa(2-ethylhexyloxy) Copper-Phthalocyanine LB Film Depending on the Film Thickness and Temperature
pp.105-109
It is well known that the metallo- phthalocyanine (MPcs) are sensitive to toxic gaseous molecules such as NO2 and also chemically and thermally stable, Therefore, lots of MPcs have been studied for the potential chemical sensor for NO2 gas using quartz crystal microbalance(QCM) or electrical conductivity. In this study, ultra-thin films of octa(2-ethylhexyloxy)copper-phthalocyanine were prepared by Langmuir-Blodgett method and characterized by using UV-VIS absortion spectroscopy and ellipsometry. Transfer condition, and characterization of LB films were investigated and preliminary results of current-voltage(I-V) characteristics of these films exposed to NO2 gas as a function of film thickness and temperature were discussed.
