Аннотация: A new blue-emitting phosphor Li3Sc2(PO4)3:Eu2+ was synthesized by a high temperature solid-state reaction method, and the crystal structure and photoluminescence properties were investigated in detail. The preferred crystallographic position of the Eu2+ ions in the Li3Sc2(PO4)3 host were determined from the structural analysis and spectroscopic properties. The as-prepared phosphor gave an intense blue emission band centered at 439 nm with the CIE coordinate of (0.1540, 0.0317) upon the excitation of the near ultraviolet light. The critical quenching concentration of Eu2+ in Li3Sc2(PO4)3:Eu2+ was about 15 mol%, and the corresponding concentration quenching mechanism was verified to be the dipole-quadrupole interaction. The fluorescence lifetime of Eu2+ emission and the thermal stable luminescence property have been investigated. Li3Sc2(PO4)3:Eu2+ was found to be a promising candidate as a blue-emitting n-UV convertible phosphor for the application in white light emitting diodes (w-LEDs).
