Abstract:

D-GSH and 1-L-Glutamyl-D-Cysteinylglycine were used as stabilizers to promote CdTe evolution in aqueous solution. We have studied the UV-Vis spectra of CdTe QDs by controlling reflux time and found that tiny differences between D-GSH and 1-L-Glutamyl-D-Cysteinylglycine in molecular structure can result in different surface states of CdTe QDs, leading to different fluorescent properties. We also discuss the reasons for these differences.

Key words: D-GSH, 1-L-Glutamyl-D-Cysteinylglycine, isomeride, fluorescent properties
