Synthesis of CdSe quantum dots in ethanol: A facile way to achieve photoluminescence with high brightness

Luminescent CdSe quantum dots are synthesized using ethanol as a solvent instead of commonly-used water or organic compounds with long alkyl chains. The strong fluorescent emission of the quantum dots is expectedly related to particle agglomeration that dramatically form a tri-level microstructural characteristic.
