Abstract
Ca9Y(PO4)7:Sm3+ phosphor was prepared via solid state reaction. The crystal structure of the phosphor was characterized by X-ray powder diffraction (XRD). The photoluminescence (PL) properties of Ca9Y(PO4)7:Sm3+
were investigated. The emission of the Ca9Y(PO4)7:Sm3+ phosphor consisted of some sharp emission peaks of Sm3+ centered at 563 nm, 600 nm, and 647 nm. The strongest one is located at 600 nm due to the 4G5/2–6H7/2
transition of Sm3+. The critical distance was calculated to be 10.5 Å. The chromatic properties of the sample Ca9Y(PO4)7:Sm3+ phosphor were located in the orange reddish region. The Ca9Y(PO4)7:Sm3+
phosphor may be potentially used as red phosphor for white light-emitting diodes (WLED).
