Refractive Index Measurements of the Beta Aluminas
Abstract
The refractive indices of selected monovalent and divalent beta' alumina single crystals have been determined using prism refraction techniques. The birefringence was found to vary from uniaxial negative to uniaxial positive depending upon the electronic polarizability of the exchanged ion. Thus, beta' alumina represents a novel material in which the magnitude and polarity of the birefringence can be tuned simply by ion exchange.
