We designed a high spatial resolution scintillation screen with a vertical ZnO nanowires structure that converts X-ray to UV-visible light. These well-distributed vertical ZnO nanowires were grown by the hydrothermal method, which plays an important role as a light guide to suppress lateral spreading. Sharp and high X-ray digital images have been obtained from a cooled-CCD camera. The best spatial resolution of 9.8 lp/mm is achieved for 2μm thick ZnO nanowires under a 30 keV monoenergetic X-ray beam. We demonstrated that these solution-growth vertical ZnO nanowires scintillation screen can provide a high X-ray image with high spatial resolution.

垂直纳米线增强 X 射线成像的空间分辨率


我们设计了一种具有垂直 ZnO 纳米线结构的高空间分辨率闪烁屏，可将 X 射线转换为紫外可见光。这些分布均匀的垂直氧化锌纳米线是通过水热法生长的，它作为光导抑制横向扩散发挥着重要作用。冷却 CCD 相机获得了清晰的高 X 射线数字图像。 2μm 厚的 ZnO 纳米线在 30 keV 单能 X 射线束下实现了 9.8 lp/mm 的最佳空间分辨率。我们证明了这些溶液生长垂直 ZnO 纳米线闪烁屏可以提供具有高空间分辨率的高 X 射线图像。
