摘要：

A series of reddish orange light-emitting NaBaLa2(PO4)(3): Sm3+(NBLP:Sm3+) phosphors are designed and synthesized in this work for the first time. The crystal structure of NaBaLa2(PO4)(3): Sm3+(NBLP) has been studied by the Rietveld refinement analysis, which shows that the NBLP belongs to eulytite-type orthophosphate. Luminescence properties of NBLP:Sm3+ phosphors were investigated in detail, including excitation and emission spectra, concentration quenching, fluorescence decay, Inokuti-Hirayama (I-H) model analysis, etc. The Commission Internationale de L'Eclairage (CIE) coordinates exhibited a shift slightly from reddish-orange (0.5782, 0.4171) to orange (0.5605, 0.4312) with the increase of Sm3+ concentration. In addition, the NBLP:Sm3+ phosphor shows good thermal stability and acceptable quantum efficiency. From the obtained results, the prepared phosphor NBLP: Sm3+ can be demonstrated as a potential orange-red luminescent material. (C) 2017 Elsevier B.V. All rights reserved.
