Yb3+/Tb3+/Er3+-doped transparent alkaline earth fluorosilicate glass ceramics containing SrF2nanocrystals were prepared and their microstructures and spectroscopic properties were investigated. The formation of SrF2nanocrystals enriched with Yb3+/Tb3+/Er3+in the glass ceramics was confirmed by XRD, HRTEM and SAED. The glass ceramics exhibited intense upconversion luminescence behaviors, owing to efficient energy transfers from Yb3+to Er3+and Tb3+and low phonon assistant non-radiative transition probabilities of excited Er3+and Tb3+. The upconversion could be enhanced significantly by increasing the annealing temperature and the luminescence color could be adjusted by varying the Yb3+/Tb3+/Er3+ratio. Upconversion of Er3+could be described as sequential energy transfer from single Yb3+to single Er3+, while upconversion of Tb3+described as cooperative energy transfer from double Yb3+to single Tb3+.
