| 中文摘要 | the thermoluminescence (tl) of zns nanoparticles is reported. the tl intensity increases as the particle size is decreased. the consistency of the size dependence of the tl with that of the surface fluorescence indicates that the tl may be related to the surface states. tl may be caused by the recombination of carriers released from the surface states or defect sites by heating. smaller particles have higher surface/volume ratio and more surface states, therefore contain more accessible carriers for tl. besides, the carrier recombination rate increases upon decreasing size due to the increase of the overlap between the electron and hole wave functions. these two effects may make the tl increase upon decreasing size of the particles. the appearance of tl prior to any radiation reveals that trapped carriers have pre-existed. the investigation of tl may provide some useful information about the surface states that may explain the size dependence of the surface fluorescence.
