Upconversion photoluminescence properties of SrY2O4：Er^3＋,Yb^3＋ under 1550 and 980 nm excitation

Er^3＋/Yb^3＋ co-doped SrY2O4 phosphors with high color purity and brightness were successfully synthesized via a solid-state reaction method.Luminescence spectrum studies showed that the main red peaks and the minor green peaks of upconversion emissions were located at approximately 634–681 nm and 54...
