(a) Room temperature resistance value for various films. (Error bar indicates variation in resistance of five samples of the same composition. A variation within indicates very good reproducibility.) (b) Bar chart showing absolute value of sensitivity, , of hybrid films of different compositions for different gases. The gas concentration in all the cases was .
Response curves of P3HT:ZnO-nanowire (1:1 composition) hybrid films for and . Insets show response curves of pure P3HT and ZnO-nanowire films. The gas concentration in all the cases was .
SEM micrographs of P3HT, hybrid of different compositions, and ZnO-nanowire thin films.
(a) GIXRD, (b) PL, (c) XPS, and (d) FTIR spectra (in the vicinity of–CS stretching vibrations of the thiophene ring) recorded for different films.
