Fig. 5From: Cd-free Cu-doped ZnInS/ZnS Core/Shell Nanocrystals: Controlled Synthesis And Photophysical Propertiesa UV-visible absorption and b photoluminescence spectra of ZnInS:Cu core CNCs as a function of Zn/In stoichiometric composition. The inset in a shows the calculated energy band gap of ZnInS:Cu CNCs. c Shift of the Cu dopant PL peak position and Cu contribution (%) with respect to total integrated emission for different CNCs having variable Zn/In ratiosBack to article page
