英文摘要	In this article, transparent oxyfluoride glass ceramics containing β-NaYF4nanocrystals were successfully prepared via Gd3+doping. Compared to conventional non-doped glasses, the thermal treatment temperature required for the precipitation of β-NaYF4nanocrystals can be lowered with the doping of Gd3+. Furthermore, under the same thermal treatment condition, more β-NaYF4nanocrystals were precipitated in Gd3+doped ones, which greatly improves the luminescence efficiency of rare earth doped glass ceramics. Possible mechanism for the Gd3+doping induced enhanced upconversion luminescence phenomenon was proposed, based on thorough structural and optical characterizations. The results revealed that the doping of Gd3+ions could decrease the crystallization activation energy and promote the formation of Y-F-Na bonding, which helps the precipitation of β-NaYF4nanocrystals. Consequently, a large enhancement in upconversion luminescence was achieved. Moreover, the strategy can be successfully applied to the development of other glass ceramic systems for various optoelectronic applications. © 2018 Elsevier Ltd and Techna Group S.r.l.
