Here, the direct synthesis β-cyclodextrin (β-CD) coated water-soluble CdTe quantum dots (QDs) by using a new ‘one pot’ method is reported. Cd(Ac)2, NaHTe, oleic acid and β-CD were used as precursors in the water–oil two phase system. The obtained CdTe QDs were characterized by luminescence spectroscopy, ultraviolet-visible (UV–vis) spectroscopy, fourier transform-infrared (FT-IR) spectroscopy, transmission...
In this paper, different sizes of glutathione-capped CdTe (GSH/CdTe) quantum dots (QDs) have been prepared directly in aqueous solution. The QDs have tunable fluorescence in the range of 510–670nm, and they also have high photoluminescence quantum yield (PLQY) without any postpreparative treatment. Furthermore, the QDs have strong resistance to photobleaching, and they also have to be considered as...
