摘　　要：采用简易的化学溶液法结合采用外延生长技术制备Nd:Bi_(2)WO_(6)/ZnS掺杂纳米复合材料。详细地研究了Nd:Bi_(2)WO_(6)/ZnS纳米复合材料的结构、光谱性质和光学性能。通过掺杂的策略,调控了Bi_(2)WO_(6)/ZnS复合结构的光学带隙调控,优化了样品对可见光的利用。当掺杂浓度为5 at%时,样品的禁带宽度最小,对可见光的吸收能力最强,此时产物的光致发光性能最低。Nd:Bi_(2)WO_(6)/ZnS nanocomposites were prepared by simple chemical solution method and epitaxial growth technique.The structure,spectral and optical properties of Nd:Bi_(2)WO_(6)/ZnS nanocomposites were investigated in detail.Through the doping strategy,the optical bandgap regulation of the Nd:Bi_(2)WO_(6)/ZnS composite structure is regulated,which improves the utilization of visible light in the visible band.When the doping concentration is 5 at%,the band gap of the sample is the smallest and the absorption of visible light is the strongest.At this time,the photoluminescence performance of the product is the lowest,indicating that it has excellent photocatalytic activity.
