ESR AND OPTICAL ABSORPTION STUDIES ON TRANSITION METAL IONS AND COLOR CENTERS IN GLASS
Abstract
The program of study of the transition metal ions in glass was concerned with a study of the Cr(3+) ion in glass. Experiments to measure the magnitude of the zero field splitting parameter /2D/ of isolated Cr(3+) ions in glass were undertaken. Attempts to measure the magnitude of the isotropic exchange coupling constant /J/ for antiferromagnetically coupled Cr(3+) ion pairs in glass were successfully undertaken and a preliminary J value was obtained. The anisotropic terms which give rise to zero field splittings of the Spin multiplets for this system are considered. Experimentally, from the frequency dependence of the ESR spectrum for this system, it was possible to obtain an estimate of the zero field splitting of the S = 1 level. The experimental color center defect studies in laser glass includes investigations of both permanent and transient color centers. A description of a theoretical investigation of trapped hole centers in glass is also given.
