The PL spectra of ScPO4:0.03Tb3+, yEu3+ (y = 0–0.05) phosphors under N-UV excitation (λex = 370 nm) and the tunable luminescence.
A series of single-phase and color-tunable Sr3NaY(PO4)3F:Eu2+, Mn2+ phosphors have been successfully prepared via the solid-state reaction.
A novel blue phosphor CAZO:Bi3+ and a color tunable phosphor CAZO:Bi3+,Mn4+ have been synthesized, characterized, and studied. The internal QY of CAZO:Bi3+,Mn4+ is as high as 89.1% due to the energy transfer efficiency from Bi3+ to Mn4+.
