摘要：
In the present communication, an attempt has been made to see the effect of Sm doping on electroluminescent properties of ZnS:Cu luminophors. The electroluminescent emission characteristics have been compared for four samples viz ZnS:Cu,Cl, ZnS:Sm, ZnS:Cu,Sm and ZnS:Cu,Sm,Cl. In the presence of Sm the spectral curves show a shift of emission band towards lower wavelength side, whereas the frequency and voltage characteristics follow the universal law of emission. No intraband transition is observed.
