| Abstract: | Mn-doped CdTe quantum dots(Mn:CdTe d-dots) were synthesized in the water.The products were characterized by photoluminescence spectra(PL),atomic force microscope(AFM),X ray powder diffraction(XRD) and energy dispersive spectrometer(EDS).The conditions,such as the reaction time,temperature,Mn2+ doped quantity,pH and the molar ratio of MPA and Cd2+,were studied.Experimental results showed that: the reaction time,temperature,pH,the molar ratio of MPA and Cd2+ had influenced on the particle size of doped quantu... |
