Preparation and up-conversion luminescence properties of Er3+-Yb3+ doped glass ceramics

Highlights: • Er³⁺-Yb³⁺ doped glass ceramic containing NaBi(MoO4)₂ is synthesized. • The effect of Er³⁺ incorporation on the deviation angle of diffraction peak is discussed. • The up-conversion luminescence properties of Er³⁺-Yb³⁺ glass ceramics is studied. -- Abstract: The molybdate precursor glass was prepared by the melting-annealing method. After heat treatment of the precursor glass, the glass ceramics containing NaBi(MoO₄)₂ crystal phase were successfully synthesized. The transmittance of the precursor glass and glass ceramics and up-conversion emission spectra at 980 nm were measured and analyzed. The effect of Er³⁺-Yb³⁺ doped concentration on the up-conversion luminescence intensity of glass ceramic samples was studied, and finally the best doped concentrations of Er³⁺ and Yb³⁺ were 0.6% and 1.0%, and the doped concentration ratio is 3:5. The Er³⁺-Yb³⁺ co-doped transparent glass ceramics containing NaBi(MoO₄)₂ have potential applications in green up-conversion luminescence.
