1. Direct observation of stacking disorder in a colloidal crystal. Author Verhaegh, Nynke A. M., van Duijneveldt, Jeroen S., van Blaaderen, Alfons, and Lekkerkerker, Henk N. W. Subjects COLLOIDAL crystals, FLUORESCENCE, LIGHT scattering Abstract Colloidal crystals of rhodamine labeled silica spheres dispersed in chloroform have been studied with fluorescence confocal scanning laser microscopy. We report the first determination of the three-dimensional crystalline stacking in the bulk of a concentrated dispersion. The structure was found to consist of a random stacking of close-packed planes. The results are compared with light scattering experiments. © 1995 American Institute of Physics.
