Abstract

Syntheses of diluted magnetic semiconductor Cd_1-yMn_yS nanoparticles varying in size from 1.9 to 3.5 nm and composition, y, from 0 to 0.3 have been performed in reverse micelles. Size and composition, y, of the particles are controlled independently. The particles are characterized by TEM, EDS, and EPR. Manganese ions are substituted randomly in the CdS matrix. Optical absorption studies show, at fixed composition, a quantum size effect. At fixed size a nonlinear variation of the band gap versus composition is observed. This effect already observed in the bulk phase is more pronounced with quantum dots.
