Synthesis, Fluorescence Properties of a Complex Probe Based on Hydroxyl Quantum Dots and Carbazole Abutment Styryl Fluorescence Dye
نویسندگان
چکیده
Hydroxyl CdTe/CdS core/shell structure quantum dots (QDs) were synthesized using mercaptoethanol as stabilizer in aqueous under N2. In addition, the QDs coated with carbazole abutment styryl (TCQ) fluorescence dye were synthesized in room temperature, and the fluorescence properties were studied. The results indicated that the peak shift of QDs fluorescence spectra can mainly be due to the change of the capping layer, resulting in the confinement energy change. The fluorescence spectra also indicated QDs and TCQ may occur to fluorescence resonance energy transfer (FRET) by the combination of QDs and TCQ fluorescence dye. The forming process and mechanisms are being investigated.
