摘要：
Interconfigurational 4f <----> 5d VUV absorption and luminescence, intra-4f(1) IR absorption and X-band EPR measurements have been carried out on CaF2:Ce3+ crystals co-doped with Na+ and Li+ ions. For both Li+ and Na+ co-doping, cubic, new tetragonal and rhombic-symmetry centres are observed. Cubic centres, which are readily observable by their infrared transitions, could not be identified and remain elusive in the EPR spectra. (C) 2004 Elsevier B.V. All rights reserved.
