(a) Evaluation of PL intensity as a function of illumination time for two PEPC thin filmsprepared from 1% and 10% in dimethylformamide (DMF) solution. The laser power is 7 mW at 325 nm (corresponding to a fluence 0.175 W·cm−2); (b) XRD spectra of PEPC thin films prepared from 1% (green line) and 10% (red line) in DMF solution.
