简介：轧了nanorods被磁控管劈啪作响和加氨系统综合，并且Tb中间的层的厚度被改变学习效果在上轧了nanorods。结果被扫描电子测试显微镜学(SEM)，X光检查衍射(XRD)，传播电子显微镜学(TEM)，高分辨率的传播电子显微镜学(HRTEM)，和光致发光(PL)系列。结果证明Tb层的厚度在形式，质量，和光性质上有明显的效果轧了nanorods。在房间温度的PL系列在368点显示出一座很强壮的排放山峰?nm和弱排出物在387点达到顶点?当Tb层是20时，为生产样品的山峰的nm，和紧张到达最大值?nm。最后，20的最佳的厚度?为综合的Tb中间的层的nm轧了nanostructures被完成。
