摘要: 用ESR成像方法探测了石英玻璃杜瓦受紫外光辐照后产生的局部晶格缺陷——F心的空间分布情况.从F心的有梯度场ESR谱和二维ESR图象可以看出,石英杜瓦中产生的F心空间分布是不均匀的,其浓度与辐照方向和辐照强度密切相关.从F心ESR散点图计算出的石英杜瓦横截面几何尺寸与实物基本相符.

Abstract: The spatial distributions of paramagnetic defect centers Fcenters in quartz Dewar after UV-irradiation were detected by ESRimaging method.It has been shown that the spatial distributions of Fcenters in the quartz Dewar are non-uniform from ESRspectrum with magnetic field gradient and 2-D ESRimages.The concentration of Fcenter is colsely related to the irradiation direction and density.The geometric size of the cross section of Dewar obtained by calculating ESRdiscrete point map of Fcenter is in agreement with the material object.
