From: Microwave-assisted synthesis of water-dispersed CdTe/CdSe core/shell type II quantum dots
Results of UV illumination treatment of the as-prepared CdTe/CdSe core/shell QDs. PL spectra of CdTe/CdSe QDs after UV treatment, which indicates that the PL intensity of the CdTe/CdSe QDs could be enhanced by the lasting time of UV illumination. The PL intensities of the as-prepared CdTe/CdSe QDs were recorded at the same absorbance values at the first excitation the absorption peak.
