Abstract
Cd1 − xMnxS nanocrystals (NCs) were successfully grown in a glass matrix and investigated by photoluminescence(PL), electron paramagnetic resonance (EPR) and magnetic force microscopy (MFM). Weverified that the luminescent properties of these NCs can be controlled both by changing thex concentration and by thermal annealing of the samples. TheEPR and PL data showed that the characteristic emission ofMn2 + ions(4T1–6A1) is only observed when this magnetic impurity is substitutionally incorporated in theCd1 − xMnxS NC core(site SI). Besides, it was observed that the emission (4T1–6A1) suppression, causedby the Mn2 + ion presencenear the surface (site SII) of the Cd1 − xMnxS NCs, is independent of the host material. The MFM images also confirmed the high quality of theCd1 − xMnxS NC samples, showing a uniform distribution of total magnetic moments in thenanoparticles.
