ABSTRACT

ZnS nanocrystals doped with Mn 2+ ions are prepared by a solution process and subsequent UV irradiation to produce the samples with different S/(Zn+Mn) ratios and/or surface modification by acrylic acids. Coordination states around Mn 2+ , ions were examined at 9 and 35 GHz by electron paramagnetic resonance spectroscopy. The Mn 2+ sites in the vicinity of 2- vacancies or carboxyl groups are observed at the frequencies more than 9 or 35 GHz, respectively, for nanocrystals, but are not for the bulk sample of 250 nm diameter. Such Mn 2+ sites enhance the photoluminescence due to d-d transition of Mn 2+ ions through energy transfer from S 2- vacancies or carboxyl groups, excited simultaneously by a light of 350 nm for exciting ZnS.
