采用共沉淀法制备了六方纤锌矿结构的Sb3+掺杂ZnO纳米荧光粉,并系统研究了不同Sb3+掺杂浓度、不同煅烧温度和时间对其发光性能的影响。借助于XRD、SEM、荧光光度计等测试手段对粉体的相组成、形貌及其光致发光性能进行了表征。结果表明:掺杂Sb3+样品的粒度小于未掺杂样品的粒度,当Sb3+掺杂浓度小于3%时,ZnO:Sb3+样品均具有纯相的六方纤锌矿结构;掺入Sb3+时会引起ZnO晶体发光强度的改变,当Sb3+掺杂浓度为2%、600℃煅烧4 h时,纳米粉具有较强的发射强度,两个主峰中心位置分别在450nm和510nm附近。
Sb3 + doped ZnO nano-powders with hexagonal wurtzite structure were prepared by co-precipitation method. The effects of Sb3 + doping concentration, calcination temperature and time on the luminescent properties were systematically investigated. The phase composition, morphology and photoluminescence properties of the powders were characterized by means of XRD, SEM and fluorophotometer. The results show that the size of Sb3 + -doped samples is smaller than that of undoped samples. When Sb3 + doping concentration is less than 3%, ZnO: Sb3 + samples have pure hexagonal wurtzite structure. When Sb3 + When the doping concentration of Sb3 + is 2% and the calcination time is 600 ℃ for 4 h, the nanopowder has strong emission intensity. The center positions of the two main peaks are around 450 nm and 510 nm, respectively.
