Orientation dependence of the ion beam and cathodoluminescence of albite

Ion beam induced luminescence and cathodoluminescence of albite produce unexpected differences between (010) and (001) aligned samples. The emission spectra are modified by temperature and different components change in their relative intensity as a result of excitation by different ion beams of H+, H-2(+) and He+. A consideration of processes which can induce the orientation dependence and the role of excitation density that influences the component features are both discussed.
