首先单看XY轴，对应于光源从片子正上方打下来，对应派派堆积，010，out of plane;单看z轴，对应于...
而且FIT2D一般是用于WAXS，不考虑掠入角引起的折射等问题的，有一定的误差。现在一般要求GIWAXS做校正...
实验室新手一枚,方向是有机太阳能电池活性层材料,在很多文献中都看到用2D-GIWAXS来分析材料的分子取向和晶体取向,度娘也没怎么清楚的解释,求大神详细解释一下,怎么看懂图谱。谢啦。下图是截取的,作为例子。图片1.png 展开 0评论 +关注 共6个回答 时岫,给排水工程师 2018-03-26回答 您好,你的问题解决了吗?
GIWAXS(掠入射广角X-射线散射有些光源称为掠入射漫反射),虽然制备的是薄膜样品,但与2D粉末衍射技术一致,在该软件中选择这个模块 常用功能:(红色为重要按钮) Exit:退出 BEAM CENTRE:标定光标中心(有标样时无需使用这个功能) FULL:自动全图显示 OUTPUT:导出数据 ...
