Research Based on Dependencies of Luminescent Properties of CdTe Quantum Dots with TGA as Surfactant

Abstract:

We investigated the optical characterization of luminescent thioglycolic acid (TGA) stabilized CdTe quantum dots (CdTe-QD) synthesized in water. The influence of stabilizing agents on the luminescent properties of water-soluble CdTe quantum dots (QDs) was described. It is found that QDs can be synthesized easily when TGA is chosen as stabilizing agent and TGA leads to preparation of highly luminescent QDs due to the secondary effects of bonds between Cd²⁺ and sulfhydryl groups. The absorption wavelength and PL stability of TGA-CdTe are also characterized. Size can be controlled between 2.0 nm to 4.0 nm. The TGA-CdTe QDs prepared at 2 h reaction time possess excellent luminescent properties.
