| 抄録 | We examined influences of the particle volume fraction φ and effective charge number Zeff on the crystal structures of charged colloids, by means of the reflection spectroscopy and Kikuchi-Kossel diffraction measurements. We employed dilute salt-free aqueous dispersions of charged polystyrene (PS) particles (the diameter d = 110 to 120 nm; Zeff = about 1300) and colloidal silica (d = 120 nm, Zeff = about 550). The PS colloids had the BCC structure at φ less than or equal to 0.01 and exhibited the structural phase transition into the FCC lattice on increasing φ. The silica colloids, which had lower Zeff, took the BCC structures at all φs examined (φless than or equal to 0.04). |
