Description

Na-codoped and only Yb-doped Yb:PbF2 crystals were successfully grown using the vertical Bridgman method. The influence of the ions codoped with Na+ on the distribution coefficients has been studied. Enhanced ∼1.0 μm emission and simultaneously suppressed upconversion emission was observed for Yb:PbF2 crystals codoped with 2 mol% NaF. A time-resolved spectroscopy study showed that the ions codoped with Na+ lengthen the fluorescence lifetime by 6%. Absorption spectra were also studied and showed that the ions codoped with Na+ can effectively suppress the formation of Yb2+ ions. (letter)
