Solid solutions in EuSc3(BO3)4-GdSc3(BO3)4 system: Phase diagram, synthesis, crystal growth, structure and luminescence

Solid solutions based on (Eu,Gd)Sc3(BO3)4 (C2/c) and Gd0.25Sc0.75BO3 (R 3) in the EuSc3(BO3)4-GdSc3(BO3)4 system were studied. Synthesis at 1250 ◦C provides wide homogeneity regions which are stable at room temperature. Melt-solution crystallization of both compounds from LiBO2-LiF flux was shown. A...

Description
Summary:Solid solutions based on (Eu,Gd)Sc3(BO3)4 (C2/c) and Gd0.25Sc0.75BO3 (R 3) in the EuSc3(BO3)4-GdSc3(BO3)4 system were studied. Synthesis at 1250 ◦C provides wide homogeneity regions which are stable at room temperature. Melt-solution crystallization of both compounds from LiBO2-LiF flux was shown. All the obtained samples have luminescence characteristic of Eu3+ with a largest peak at 615 nm corresponding to the 5D0 → 7F2 transition. In this series the luminescence intensity monotonically increases with an increase of Eu content. The largest quantum yield of luminescence (53 %) in the EuSc3(BO3)4 GdSc3(BO3)4 system is demonstrated by EuSc3(BO3)4 sample.
