采用电沉积法在掺ga的ZnO/钠石灰玻璃上制备了新型（0001）取向ZnO垂直纳米线（vnws）用于x射线成像的闪烁体，并在同步辐射设备上对其发光特性进行了估计。与zno层闪烁体相比，ZnO-vnws闪烁体具有较强的发光能力，并且在CMOS图像上的分辨率有所提高，但其发光性能较Lu3Al5O12:Ce3+有所下降。光发射特性与纳米结构及其产生的光致发光特性密切相关。(C) 2015 AIP出版有限责任公司
Newly designed scintillator of (0001)-oriented ZnO vertical nanowires (vnws) for X-ray imaging was prepared on a Ga-doped ZnO/soda-lime glass by electrodeposition, and the light emission feature was estimated in a synchrotron radiation facility. The ZnO-vnws scintillator revealed a strong light emission and improved resolution on CMOS image compared with that for the ZnO-layer scintillator, although the light emission performance was deteriorated in comparison to the Lu3Al5O12:Ce3+. The light emission property closely related to the nanostructure and the resultant photoluminescence characteristic. (C) 2015 AIP Publishing LLC.
