Comparison, colloid science investigations

The electro-optical responses of colloidal systems were detected by reflection spectroscopy and by the variations of scattered light intensity. Induced variations in the reflection spectra of colloidal crystals turned out to be very sensitive to electroacoustic effects, while the experimental setup of the second method permits direct comparison with numerous data on anisometric colloids. Investigations into reflection spectroscopy were carried out by Okubo and coworkers at Gifu University (Japan), and the light scattering studies by Stoimenova, Okubo, and coworkers at the Bulgarian Academy of Sciences. The essential parts of the results are due to our joint research.
