| 英文摘要 | Chain-like mg-doped zno nanoparticles were prepared using a wet chemical method combined with subsequent heat treatment. the blueshifted near-band-edge emission of the doped zno sample with respect to the undoped one was investigated by temperature-dependent photoluminescence. based on the energy shift of the free-exciton transition, a band gap enlargement of similar to 83 mev was estimated, which seems to result in the equivalent shift of the bound-exciton transition. at 50 k, the transformation from the donor-acceptor-pair to free-to-acceptor emissions was observed for both the undoped and doped samples. the results show that mg doping leads to the decrease of the acceptor binding energy.
