Analysis of the off-center effect of Cu + in alkali halides using crystal-field theory

Analysis of the off-center effect of Cu + in alkali halides using crystal-field theory We have found that the relative intensity of the A 1 g 1 → 1 E g and A 1 g 1 → 1 T 2 g crystal-field components of the 3 d 10 →3 d 9 4 s transition of Cu + in alkali halide hosts provides a measure of the Cu + ground-state off-center displacement along the 111 axis. This is shown by deriving the crystal- field potential that describes the off-center effect of Cu + , and then calculating the transition moments to the E g 1 and T 2 g 1 final states. By analyzing the spectra of Cu + in numerous alkali halide hosts, it is found that the degree of off-center displacement increases with the lattice constant of the alkali halide. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Physical Review B American Physical Society (APS)

Abstract

We have found that the relative intensity of the A 1 g 1 → 1 E g and A 1 g 1 → 1 T 2 g crystal-field components of the 3 d 10 →3 d 9 4 s transition of Cu + in alkali halide hosts provides a measure of the Cu + ground-state off-center displacement along the 111 axis. This is shown by deriving the crystal- field potential that describes the off-center effect of Cu + , and then calculating the transition moments to the E g 1 and T 2 g 1 final states. By analyzing the spectra of Cu + in numerous alkali halide hosts, it is found that the degree of off-center displacement increases with the lattice constant of the alkali halide.
