Abstract

Abstract:

Sm-doped zinc oxide quantum dots（ZnO QDs） with good dispersibility were prepared by studying different amount-of-substance ratiosof alkali-zinc and samarium-zinc.It was characterized by UV-vis spectroscopy（UV-vis）,X-ray diffraction（XRD）,field emission transmission electron microscopy（TEM）,energy dispersive X-ray spectroscopy（EDS） and X-ray photoelectron spectroscopy（XPS）.The results showed that ZnO QDs prepared with n（Zn）∶n（OH^-）=1∶1 and Sm doping amount of 4%（amount-of-substance fraction） had the strongest fluorescence emission intensity under UV excitation at 383 nm.It was also found that the doping of rare earth Sm ions was related to the formation of oxygen vacancies（OV） in ZnO QDs.The oxygen vacancy concentration of Sm-doped ZnO QDs was higher than that of undoped,and the higher the concentration of oxygen vacancies in ZnO QDs,the stronger the fluorescence emission intensity.

Key words: ZnO QDs, Sm, doping, fluorescence
