Abstract : A series of monovalent copper containing Beta -alumina single crystals have been prepared by standard ion exchange techniques. The crystals exhibit strong luminescence which we attribute to the 3d94s--3d10 interconfigurational transition. The peak wavelength of this transition can be varied by 135nm by the presence of other cations in the beta -alumina conduction plane, allowing the luminescence to be varied through out the visible spectrum. Single pass gain measurements of several of these crystals show gains of the order of 0.1/cm, suggesting the potential use of these materials for solid state tunable lasers. Keywords: Copper, Beta, Alumina, Emission spectroscopy, Ion exchange tunable solid state lasers.
