中文摘要	the temperature dependences of the orange and blue emissions in 10, 4.5, and 3 nm zns:mn nanoparticles were investigated. the orange emission is from the t-4(1)-(6)a(1) transition of mn2+ ions and the blue emission is related to the donor-acceptor recombination in the zns host. with increasing temperature, the blue emission has a red-shift. on the other hand, the peak energy of the orange emission is only weakly dependent on temperature. the luminescence intensity of the orange emission decreases rapidly from 110 to 300 k for the 10 nm sample but increases obviously for the 3 nm sample, whereas the emission intensity is nearly, independent of temperature for the 4.5 nm sample. a thermally activated carrier-transfer model has been proposed to explain the observed abnormal temperature behaviour of the orange emission in zns:mn nanoparticles.
