Abstract

The $NO_2$ gas-detection characteristics were investigated using the functional organic Langmuir-Blodgett(LB) films of Copper-tetra-tert-butylphthalocyanine(CuTBP). The optimum conditions for a film deposition were obtained through a study of $\pi$-A isotherms, and the deposited film status was confirmed by the ellipsometry measurements. The $NO_2$ gas response experiments under 200 ppm concentration at room temperature show that there are increment of electrical conductivity by 40 times and 25 seconds of response time, and 40 seconds of recovery times.
