摘要：
The Ca9La(PO4)(5)(SiO4)Cl-2:Dy3+ (CLPSCI:Dy3+) powder phosphor with apatite structure has been successfully synthesized via high -temperature solid state method. Single phase in such phosphor was verified through X-ray diffraction (XRD) technique. The Dy ions concentration dependent luminescence properties including emission, excitation and lifetimes of Dy ions were characterized using photoluminescence (PL) spectroscopy. The results showed that CLPSCI:Dy3+ phosphor could efficiently assimilate the n-UV light and emit blue (similar to 486 nm) and yellow light (similar to 578 nm), originating from the f-f transitions of Dy3+. The critical Dy3+ quenching concentration (QC) was determined to be about 12 mol%. The concentration quenching mechanism was also determined to be dipole-dipole interaction. (C) 2016 Elsevier B.V.
