    Synthesis and photoluminescent properties of ZnO:Cu/ZnO core/shell nanocrystals

    ZnO:Cu/ZnO core/shell nanocrystals are synthesized by a two-step solution-phase process. The morphology, structure and optical properties of the samples are detected by scanning electron microscopy, Raman, abs...

    Defect-related visible luminescence of ZnO nanorods annealed in oxygen ambient

    ZnO nanorods prepared by a solution-phase method are annealed at different temperatures in oxygen ambient. The luminescence properties of the samples are investigated. In the same excitation condition, the pho...

    Size influence on the fluorescence decay time of ZnS:Mn2+ nanocrystals

    ZnS:Mn2+ nanocrystals (NCs) with particle size from 1.9 nm to 3.2 nm are synthesized via chemical precipitation method with different [S2−]/[Zn2+] ratios. The size dependent decay for Mn emission exhibits a doubl...

    Influence of reaction temperature on the formation process of ZnO quantum dots and the optical properties

    ZnO quantum dots (QDs)with the sizes of 3.0–5.6 nm are synthesized by solution-phase method at different temperatures. We find that temperature has great influence on the size of ZnO QDs. The growth process is...
