Luminescence properties of Pr3+-doped transparent oxyfluoride glass-ceramics containing BaYF5 nanocrystals

► The Pr3+ ions have been incorporated into BaYF5 nanocrystals. ► The optimal concentration of Pr3+ in glass ceramic changes on temperature. ► The lifetime of Pr3+ in the glass ceramic is slightly shorter than that in glass. ► The luminescence intensity of Pr3+ in nanocrystals is stronger than that in glass.
