| 内容記述 | The present study describes a simultaneous and highly reproducible large-scale synthesis of six (and more) colors of size-homogeneous and highly luminescent CdSe quantum dots in a single reaction, controlled by a slow-increasing temperature gradient. The described protocol allows a precise control and a synchronized isolation of aliquots of CdSe nanocrystals with defined sizes, avoiding disturbance of the growth of nanocrystals (existing in the reaction mixture) to the isolation of the next aliquot. The obtained quantum dot fractions are of high quality (in 95% size-homogeneous) and have sharp photoluminescence spectra (fwhm ~ 30 nm), quantum yields of 45-70% (in organic solvent), and a lack of aggregation in organic solvents. The method is environmentally friendly as it ensures almost complete utilization of the precursors and productive yield ~95%. | |||||
