中文摘要	the pl spectra for the 10, 4. 5, 3. 5, 3, 1 nm sized zns:mn2+ nanoparticles and corresponding bulk material under different pressures were investigated. the orange emission band originated from the t-4(1)-(6)a(1) transition of mn2+ ions showed obvious red shift with the increasing of pressures. the pressure coefficients of mn-related emissions measured from bulk, 10, 4. 5, 3.5 and 3 nm samples are -29.4 +/- 0.3, -30.1 +/- 0.3, -33.3 +/- 0.6, -34.6 +/- 0.8 and -39 +/- 1 mev/gpa, respectively. the absolute value of the pressure coefficient increases with the decrease of the size of particles. the size dependence of crystal field strength dq and racah parameter b accounts for the size behavior of the mn-related emission in zns:mn nanoparticles. the pressure behavior of mn-related emission in the 1 nm sized sample is somewhat different from that of other nanoparticles. it may be due to smaller size of 1 nm sample and the special surface condition since zns nanoparticles are formed in the cavities of ziolite-y for the 1 nm sample.
