摘      要：In II-VI group,the doping in CdTe nanocrystals（NCs） is more difficult than other *** this communication,CdTe nanocrystals containing Cu impurities were carefully synthesized based on controlled reverse cation exchange process between as-prepared Cu7Te5nanocubes and Cd2+*** well-defined Cu7Te5nanocubes,the obtained CdTe NCs kept the original *** concentration of Cu impurities in CdTe NCs was controlled by the regulation such reverse cation ***,the regulation from band gap（BG）photo luminescence（PL） to the coexistence of the bandgap emission,dopant emission,and surface-state emission was *** tailoring from undoped to doped emission in the case of Cu impurities is helpful to study the Cu related doping in telluride NCs.
