(Color online) The PL spectra of bare ZnO nanorods, bare P3HT film, and ZnO/P3HT NCs at 300 K. The inset shows the decay curves of the PL spectra of bare P3HT and P3HT in ZnO/P3HT NCs detected at 720 nm.
(Color online) The normalized PL spectra of P3HT CPs and ZnO/P3HT NCs at 300 K. The dotted curves are component Gaussian fitting results of the PL spectra of ZnO/P3HT NCs. The inset shows the band alignment of ZnO/P3HT NCs.
(Color online) The excitation intensity dependence of the IR PL peak position at 300 K. The inset shows PL spectra of ZnO/P3HT NCs under different excitation intensity at 300 K.
(Color online) The dependence of the Gaussian peak energy on the cubic root of the excitation intensity.
