Abstract: The hydrothermal technique is introduced into the synthesis of glutathione-stabilized ZnCdSe QDs. By incorporating cadmium ions into the pre-prepared ZnSe QDs, with continuously heating, the preparation of alloyed ZnCdSe QDs was realized. The bandgap emission dominated the emission spectra in 15 minutes.

Abstract: We review our recent experimental findings by optical orientation spectroscopy that show efficient spin relaxation within semiconductor spin detectors to be an important factor limiting efficiency of spin injection in spin light-emitting structures based on ZnCdSe/ZnMnSe and InGaN/GaMnN. We provide evidence for the physical mechanism responsible for the observed efficient spin relaxation that accompanies momentum and energy relaxation of excitons/carriers. These findings call for increasing efforts in suppressing spin relaxation in spin detectors.
