Steady state emission and excitation of PDPB nanofibers and PDPB-ZnO light harvesting nanoheterojunction.
Room temperature PL spectra of (a) PDPB (c) PDPB-ZnO at different excitation wavelengths. The excitation spectra of (b) PDPB (d) PDPB-ZnO monitored at different emission maxima are shown. All spectra were recorded in ethanol.
