Donor Centres Involved into Downconversion in Yb-Doped Molybdate and Tungstate Single Crystals

Different versions of quantum cutting mechanisms in Yb doped Scheelite-like molybdate and tungstate single crystals were studied, with participation of various schemes of donor-acceptor interaction (various kinds of donor centres: self-trapped excitons at molybdate/tungstate complexes; high-lying ex...

More Information
Summary:Different versions of quantum cutting mechanisms in Yb doped Scheelite-like molybdate and tungstate single crystals were studied, with participation of various schemes of donor-acceptor interaction (various kinds of donor centres: self-trapped excitons at molybdate/tungstate complexes; high-lying excited states of Yb 3+ ion; Yb 2+ ion; traps based on cation and oxygen vacancies; accidental impurities.). All the versions were rejected.
