P2.8.13 Nitrogen Dioxide Sensing Characteristics of Spin Coated Unsubstituted Copper Phthalocyanine Films

S. D. Chakane, A. M. Datir & V. S. Ghole
Copper phthalocyanine (CuPc) synthesized chemically was used for making CuPc thin films using spin coating technique. Spin coated films of unsubstituted CuPc films annealed at 150°C for 2 hrs were used to study NO2 gas sensing characteristics. a- phase of CuPc is noticed by X-ray diffraction and UV-Visible absorption spectra. IR spectra of undoped CuPc films and doped CuPc films with NO2 revealed that, doping of nitrogen dioxide modifies and deletes some of the bands....
