Abstract
Polarized electronic absorption spectra are reported for Er3+ and Yb3+ dope d into a gadolinium calcium oxoborate (GdCOB) host. The transitions can be assigned using a model in which the lanthanide ion occupies a single C-s si te in the host lattice. The infrared spectra of the host are utilized in th e assignment of one- and two-centre vibronic transitions. (C) 2001 Elsevier Science B.V. All rights reserved.
