本文报道了一种原位透射电镜法制备三维镍纳米珠的方法。将氟化镍转化为三维多孔的，部分氟耗尽的聚集体显示为中间状态，随后转化为金属珠。微珠尺寸范围为10-600 nm，可通过材料厚度和光束强度进行控制。该材料被发现对镍点、环和线的形成敏感，通过聚焦暴露在不同的光束形状下。
We report an in-situ transmission electron microscope method for the fabrication of three dimensional nickel nanobeads. Conversion of nickel fluoride into a three dimensional porous, partially fluorine depleted aggregate is shown as intermediate state, followed by transformation into metallic beads. The bead size ranges from 10-600 nm and can be controlled via materials thickness and beam intensity. The material is found sensitive for the formation of nickel dots, rings and lines by focused exposure with various beam shapes.
