Abstract :
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.
