使用高分辨透射电子显微镜在室温台上通过电子束照射MoO3 ,制备钼及钼的亚氧化物纳米微粒 .实验发现微米级MoO3 颗粒在强度为 1 0 2 1e/cm2 ·s的电子束照射下转变为纳米级亚氧化钼 ,经过电子束的进一步照射后 ,亚氧化钼转变为钼 .这种现象可能是由于电子束的激发作用和通过“撞击”效应而使原子发生错排引起氧原子分离造成的 . The high-resolution transmission electron microscope was used to irradiate MoO3 by electron beam on a room temperature stage to prepare molybdenum and molybdenum sub-oxide nanoparticles. It was found that micron-sized MoO3 particles were transformed under electron beam irradiation with an intensity of 1021e / cm2 · s Is a nano-scale molybdenum oxide, after further irradiation by the electron beam, the molybdenum oxide is transformed into molybdenum, which may be caused by the excitation of the electron beam and the dislocation of the atoms by the “impact” effect and the separation of the oxygen atoms of .
