摘要
The increase in g factors with decreasing diameters of the nanocrystals were observed by electron paramagnetic resonance (EPR) experiments in ZnS:Mn2+ nanocrystals embedded in pyrex glass matrix. These increases are due to the hybridization between s and p states of ZnS and d states of the Mn ions by quantum confinement effects. The experimental results can be well described according to Cardona model using k.p perturbation analysis. (C) 2000 Elsevier Science S.B. All rights reserved.
