Abstract
In this paper we demonstrate a simple backscattering experiment applied to four different systems forming mesoscopic structures. We observe the transition from crystallized to disordered electrostatically stabilized latex suspensions where the crystal structure is clearly body-centered cubic (bcc). Also, a space-filling face-centered cubic (fcc) arrangement for a sterically stabilized latex is observed. Further, an extension of previous scattering results on an undulation-stabilized lamellar phase (Lα) in a binary non-ionic surfactant-water system is presented. Finally, the application to an electrostatically stabilized gel phase with lamellar ordering (Lβ) of relatively stiff membranes below the Krafft-temperature is performed. All these systems are attractive because of the brilliant colors they display upon illumination with white light.
