Abstract

The article presents the high-temperature solid-phase synthesis of Ba3Yb(PO4)3:x at.% Tb3+ phosphors, which exhibit excellent thermal stability and high quantum yield. The study investigates the crystal structure, luminescent properties, and thermal quenching behavior of these phosphors, demonstrating their potential for applications in solid-state lighting and UV-pumped LEDs. The optimal doping concentration of Tb3+ ions is found to be 14 at.%, resulting in a narrow-band green emission with a full width at half maximum of only 10 nm. The phosphors also show good thermal stability at 160°C and a quantum yield of 55.8%, making them a promising material for advanced lighting applications.
