The luminescence properties of ytterbium ions in strontium haloborates were studied under optical, X-ray and synchrotron excitation. The coexistence of Yb ions in two valence states (divalent and trivalent) was detected in the Sr 2 B 5 O 9 X : Yb (X โ€ซุโ€ฌ Cl, Br) powder materials prepared in a slightl
