CdSe quantum dots (QDs) were synthesized by a hot-bubbling strategy

Abstract

A hot-bubbling strategy was studied to synthesize CdSe quantum dots. The synthetic parameters including temperature and growth time, were studied to show great influence on the optical properties. At the different reaction time CdSe quantum dots could emit fluorescence of different color, ranging from green to red, under the ultraviolet lamp which had irradiation of 365nm. The size of CdSe quantum dots was adjusted by the temperature and reaction time. CdSe quantum dots with sphalerite structure were prepared by this method.
