中文摘要	zns:mn nanoparticles of the cubic zinc blende structure with the average sizes of about 3 nm were synthesized using a coprecipitation method and their optical and magnetic properties were investigated. two emission bands were observed in doped nanoparitcles and attributed to the defect-related emission of zns and the mn2+ emission, respectively. with the increase of mn2+ concentration, the luminescence intensities of these two emission bands increased and the zns emission band shifted to lower energy. based on the luminescence excitation spectra of mn2+, the 3d(5) level structure of mn2+ in zns nanoparticles is similar to that in bulk zns:mn, regardless of mn2+ concentration. magnetic measurements showed that all the samples exhibit paramagnetic behavior and no antiferromagnetic interaction between mn2+ ions exists, which are in contrast to bulk zns:mn.
