A Study on the NO$_2$ Gas Detection Characteristics of Octa-dodecy1oxy Copper-Phthalocyanine LB Films

Octa-dodecyloxy Copper-Phthalocyanine LB 막의 NO$_2$ 가스 탐지 특성에 관한 연구

In this study, ruin films of Octla-dodecyloxy copper-phthalocyanine were prepared by Langmuir-Blodgett (LB) method and characterirzed by using UV-Vis absorption spectroscopy and ellipsometry. [1],r[2] Optimal transfer condition of LB films was investigated and preliminary results of current-voltage(1-V) characteristics of these films exposed to NO$_2$ gas as were discussed functions of film thickness, temperature and NO$_2$ gas concentration.
