Description
In this research, CdSe QDs were synthesized via a microwave approach. ZnSe shell was grown on the CdSe QDs using a simple, room temperature and rapid photochemical approach. Synthesized QDs were characterized by means of the different analyses such as XRD, FESEM, TEM, EDAX, UV–Vis and PL. CdSe synthesized QDs indicated a broad band (FWHM of about 120 nm) yellow surface trap states emission between 450 and 800 nm. By successful growth of the ZnSe shell broad band trap states emission of the CdSe QDs was completely converted to a narrow band and high intense blue emission with FWHM of about 40 nm which is a unique result for water soluble QDs.
