| Abstract: | CdTe quantum dots(QDs) were synthesized directly in aqueous solution by using thioglycolic acid as the stabilizer.And CdTe QDs self-assembled monolayers(SAMs) were fabricated onto the quartz surface.The assembly conditions such as polyelectrolyte concentration,assembly time and polyelectrolyte assembled layers were investigated,and the SAMs were characterized via UV-vis absorption spectra,fluorescence spectra,confocal fluorescence microscope and atomic force microscopy.A fast and sensitive method was establ... |
