Abstract

The $NO_2$ gas-detection characteristics were investigated using the functional organic Langmuir-Blodgett(LB) film of Tetra-3-hexadecyl-sulphamoylcopperphthalocyanine(HDSM-CuPc). A surface pressure of 30mN/m was obtained as a proper one for a film deposition. A deposited film status was confirmed by electrical and optical methods such as UV/visible absorption spectra and current-voltage(I-V) characteristics. The $NO_2$ gas response experiments under 200ppm concentration show that there is not increment of electrical conductivity in room temperature and is identified by UV/visible absorption spectra. But There are some increments of electrical conductivity in $160^{\circ}C$.
