Abstract:

Stark energy levels of Eu3+ ( 4f(6)) ions in CdF2 - CaF2: Eu epitaxial superlattices on Si have been measured by laser spectroscopy and calculated in an exchange charge model. Two types of centre have been considered in the CaF2 layer: an `interface centre', close to the CdF2/ CaF2 interface, and a `remote centre' located in the core of a layer. The influence of distortion, created by the silicon substrate, has been taken into consideration. The calculations confirmed a previously suggested `electron' model of the interface centre.
