Abstract
Fitting a crystal-field model to published spectra shows the dominant crystal field felt by the Er ion in codoped samples of Si:Er possesses T-d symmetry. This leads to a proposal that the role of the codopants is to decouple the Er from the silicon phonons. Support for this prop osal is found in the high-temperature luminescence quenching results.
