Abstract
We report on the Ag-, Fe-, and Co-doping of InP/ZnSe QDs using the growth-doping method. Doping the InP/ZnSe NCs with Ag caused a red-shift in the emission spectra with increasing dopant levels while the PL intensity decreased. Fe-doping resulted in blue-shifted emission spectra. The cobalt-doping (Co-doping) had no effect on the emission peak position. Instead, it had a quenching effect on the PL intensities. The HRTEM images showed well-defined lattice fringes for the doped InP/ZnSe NCs while the XRD analyses showed that they retained their zinc blende structure even after doping.
