Abstract
A CdTe quantum dot modified with thioglycolic acid as stabilizer was prepared. The structure of CdTe quantum dots was characterized by IR, UV and fluorescence spectra, transmission electron microscopy (TEM) scanning and X-ray diffraction (XRD). The effects of reactants, temperature, time and PH on the luminescence properties of the quantum dots were investigated. It is found that the quantum dots have strong fluorescence intensity. The synthesized QDS have small and uniform particle size and high crystallinity. The optimum conditions were determined as follows: n (Cd2+): n (Te2-): n (TGA) = 2:1:4, heating temperature 140°C, reaction time 60min, pH 11.
