Optical Properties of Europium-Doped Potassium Chloride Laser Window Materials.

Abstract

A study of lattice defect equilibria in the KCl:Eu crystal KC.01ECH97 has been undertaken using optical absorption, electron spin resonance and ionic conductivity. These techniques reveal that the predominant specie of the Eu ion is Eu(++), in the form of Eu(++)-vacancy complexes at room temperature. The ultraviolet absorption bands of Eu(++) that occur at 243 and 330 nm have been used to allow a non-destructive determination of the Eu(++) content. The room temperature absorption coefficient of the 243 and 330 nm bands have been calibrated by polarographic and ionic conductivity, such that the relationship between the optical absorption coefficient, alpha, and Eu(++) content is given by: Mole % Eu(++) = .00043 alpha.
