英文摘要	The pressure behavior of mn2+ emission in the 10-, 4.5-, 3.5-, 3-, and 1-nm-sized zns:mn2+ nanoparticles is investigated. the emission shifts to lower energies with increasing pressure, and the shift rate (the absolute value of the pressure coefficient) is larger in the zns:mn2+ nanoparticles than in bulk. the pressure coefficient increases with the decrease in particle size with the 1-nm-sized particles as an exception. pressure coefficient calculations based on the crystal field theory are in agreement with the experimental results. the pressure dependence of the emission intensity is also size dependent. for nanoparticles 1 and 3 nm in size, the luminescence intensity of mn2+ decreases dramatically with increasing pressure, while, for bulk and particles with average sizes of 3.5, 4.5, and 10 nm, the luminescence intensity of mn2+ is virtually unchanged at different pressures. the bandwidth increases faster with increasing pressure for smaller particles. this is perhaps due to the fact that there are more mn2+ ions at the near-surface sites and because the phonon frequency is greater for smaller particles. these new phenomena provide some insight into the luminescence behavior of mn2+ in zns:mn2+ nanoparticles.
