这张图像，我乍一看还以为是钨灯丝的呢， 但总觉得比钨灯丝图像质量好。信息栏中的14mm让我坚信，这个图像一定不是钨灯丝扫描电镜拍摄的。有可能是六硼化镧灯丝或者场发射电子枪。google 结果：

These are Zinc Oxide (ZnO) nanoparticles, magnified 23,000 with gold contamination
by complete serendipity, the gold shouldn't be there! The picture was taken
using an Field Emission Scanning Electron Microscope (SEM). The gold shows
up as very bright spots and may well of affected shape and clarity of the
ZnO nanoparticles during synthesis of the ZnO thin film on a glass substrate.

这是操作者的问题，FEG SEM的加速电压本来就不应该用那么高~

金颗粒有这么大？英文作者是想表达金对ZnO本身有干扰？
