| 中文摘要 | hierarchical heterostructures of zinc antimonate nanoislands on zno nanobelts were prepared by simple annealing of the polymeric precursor. sb can promote the growth of zno nanobelts along the [552] direction because of the segregation of sb dopants on the +(001) and (110) surfaces of zno nanobelts. furthermore, the ordered nanoislands of toothlike znsb2o6 along the [001](zno) direction and rodlike zn7sb2o12 along the [110](zno) direction can be formed because of the match relation of the lattice and polar charges between zno and zinc antimonate. the incorporation of sb in a zno lattice induces composition fluctuation, and the growth of zinc antimonate nanoislands on nanobelt sides induces interface fluctuation, resulting in dominance of the bound exciton transition in the room temperature near-band-edge (nbe) emission at relatively low excitation intensity. at high excitation intensity, however, auger recombination makes photogenerated electrons release phonon and relax from the conduction band to the trap states, causing the nbe emission to gradually saturate and redshift with increasing excitation intensity. the green emission more reasonably originates from the recombination of electrons in shallow traps with doubly charged v-o** oxygen vacancies. because a v-o** center can trap a photoactivated electron and change to a singly charged oxygen vacancy v-o* state, its emission intensity exhibits a maximum with increasing excitation intensity. |
