英文摘要	The influence of stabilizing agents and reaction time on the luminescent properties of water-soluble cdte quantum dots (qds) was discussed. the thioglycolic acid (tga)-cdte ods were characterized by tem, xrd and ftir. it is found that larger-size qds can be synthesized more easily when l-cysteine (cys) or golutathione (gsh) is chosen as stabilizing agent and tga is proper to prepare highly luminescent qds because of the effect between cd(2+) and sulfhydryl group. furthermore, the absorption wavelength, full width at half maximum (fwhm), stokes shift, photoluminescence (pl) quantum yield and pl stability of tga-cdte are strongly dependent on reaction time, in which the absorption wavelength changes against reaction time with an exponential function. the tga-cdte qds prepared at 2 h possess more excellent luminescent properties.
