Spectral-kinetic and photochemical properties of Ce3+: Na4Y6-xYbxF22 single crystals

The spectral-kinetic characteristics of Ce3+ ions doped Na4Y6-xYbxF22 (x=0-0.05) single crystals were studied. Ce3+ ions 5d-4f interconfigurational fluorescence quantum yield versus Yb3+ ion codopant concentration was measured. Pump-induced color center absorption spectra were studied and the efficiency of Yb3+ ions codoping antisolarant crystal-chemical technique applied to Na4Y6F22:Ce3+ was demonstrated. The optimal Yb3+ ions content from the point of view of effective tunable laser action was estimated. The obtained results allow proposing Na4Y6-xYbxF22 as a new prospective photochemically stabilized material for UV/VUV application.
