Abstract

Abstract: A series of orange-red emitting Ba2 Y3 (SiO4 )3 F: x Sm 3+ (0.003≤ x ≤0.08) fluorosilicate apatite phosphors was synthesized by the convenient solid-state reaction. X-ray diffraction and photoluminescence spectra were utilized to characterize the structure and luminescence properties of the as-synthesized phosphors. The emission spectra of the Ba2 Y3 (SiO4 )3 F:Sm 3+ phosphors consisted of some sharp emission peaks of Sm 3+ ions centered at 564, 601, 648, and 710 nm. The strongest one is located at 601 nm due to 4 G5/2 – 6 H7/2 transition of Sm 3+, generating bright orange-red light. The optimum dopant concentration of Sm 3+ ions in Ba2 Y3 (SiO4 )3 F: x Sm 3+ is around 3 mol% and the critical transfer distance of Sm 3+ is calculated as 26 Å. The quenching temperature is above 500 K. The CIE chromaticity coordinates of the Ba2 Y3 (SiO4 )3 F:0.03Sm 3+ phosphors is located in the orange reddish region. The Ba2 Y3 (SiO4 )3 F:Sm 3+ phosphors may be potentially used as red phosphors for white light-emitting diodes.
