Investigation of multiple centers in U3+:CaF2 single crystals

U3+:CaF2 single crystals with different dopant concentrations were grown in the presence or absence of PbF2 as oxygen scavenger by TGT. Multiple centers, at least including (Uca3+ - OF2-) and (Uca3d+- Fi-), were investigated by absorption spectra measured in the wavelength range of 190-2500 nm.Absor...
