Abstract

Tm³⁺doped NaCa₃Bi(PO₄)₃F blue-emitting phosphors have been synthesized following a conventional high-temperature solid-state reaction. Their phase purity, optical characteristics were systematically studied. The results show that the optimal doping concentration of Tm³⁺was 0.05. Electric multipole interaction was proposed as the mechanism for concentration quenching in NaCa₃Bi(PO₄)₃F materials. Furthermore, the NaCa₃Bi(PO₄)₃F:0.05Tm³⁺ fluoresces blue with color coordinates (0.1592, 0.0346). The results indicated that NaCa₃Bi(PO₄)₃F:Tm³⁺ phosphors could participate in fabricating the w-LEDs as the blue component.
