摘要

通过简单的工艺，成功地合成了均匀且优化的纳米ZnO薄膜。根据合成温度的变化对生长条件进行了调整；从300°C到450°C，导致ZnO的形貌、发光性能和ZnO薄膜的厚度发生了显著的变化。这些结构和光学性质的变化允许在不同的波长发射。氧化锌薄膜的发光颜色与氧化锌纳米结构的缺陷程度有关。由于高浓度的Zni-VZn和CB-VO跃迁，光致发光结果和CIE色度分析显示了三个不同的发射波段：黄橙色，绿色和青色。该合成表明其集成到可扩展的制造工艺中，以获得用于发光器件的纳米结构ZnO薄膜。

Defect-driven color emissions in nanostructured ZnO films synthesized by two-step ultrasonic spray pyrolysis

Homogeneous and optimized nanostructured ZnO films were successfully synthesized by a simple technique. The growth conditions were modified from the change in synthesis temperature; from 300 to 450 °C, leading to significant modifications in ZnO morphology, luminescent properties and thicknesses of ZnO films. These structural and optical properties changes allowed emissions at different wavelengths. The color of emissions from ZnO films are according to defect levels of ZnO nanostructures. Photoluminescent results and CIE chromaticity analysis demonstrated three different emission bands: yellow-orange, green and cyan due to high concentration of Z_ni-V_Zn and CB-V_O transitions. This proposed synthesis suggests its integration into scalable fabrication process for obtain nanostructured ZnO films for luminescent devices.
