Single-Crystal MgO Hollow Nanospheres Formed in RF Impulse Discharge Plasmas

Figure 4

(a) TEM image of a few nanoparticles and (b) electron refraction pattern for these particles. The rings radii correspond to refraction positions for MgO crystal. This dotted pattern shows that the spherical hollow nanoparticles are consisted of single crystal of MgO.
