| dc.description.abstract | Distinctive spectroscopic characteristics are observed in colloidal perovskite CsPbBr3 quantum dot (QD) dispersed in octane doped with PPO. As the content of CsPbBr3-QD increases, the emission and the absorption energies decrease due to QD-cluster formed in case of the inter-QD distance smaller than diameter of QD. Spectroscopic evidences supporting QD-cluster are found in the Urbach energy and the carrier lifetime. Unusual absorption lines showing explicit QD dependence are observed in Fourier-transform infrared spectra, which is explained by vibrational modes of bound PPO hybridized with CsPbBr3-QD. | - |
