Colloidal crystals formed with attractive interactions are used for in-situ observations of homogeneous nucleation processes in density-matched dispersion. We found globular and plate-like polycrystalline clusters stably suspended in the dispersion. Both clusters rotated randomly and moved freely with suspending in the dispersion. They were probably formed through homogeneous nucleation processes.

原位观察密度匹配条件下吸引相互作用形成的胶体晶体的均匀成核

通过吸引相互作用形成的胶体晶体可用于密度匹配分散体中均匀成核过程的原位观察。我们发现球状和板状多晶簇稳定地悬浮在分散体中。两个簇都随机旋转并自由移动并悬浮在分散体中。它们可能是通过均质成核过程形成的。
