Synthesis of water-soluble CdTe nanocrystals with high photoluminescence quantum yield and narrow fluorescence emission spectra (see Figure) is developed under the conditions of low precursor concentration and moderate temperature of hydrothermal growth. The relatively high temperature accelerates the particle growth rate and enhances the photoluminescence quantum yield.
