title: Synthesis and luminescence characterization of a new yellowish-orange phosphor: Ba2B10O17:Sm3.
abstract: A new yellowish-orange emitting phosphor, Ba2B10O17:Sm3+for use as a white light-emitting diode (W-LED) was synthesized by a solid-state reaction method. The X-ray diffraction results indicated that a pure Ba2B10O17material was obtained. As a potential yellowish-orange luminescent material for W-LEDs, the Ba2B10O17:Sm3+phosphor could be excited effectively by near-ultraviolet (n-UV) light and exhibited yellowish-orange emission centered at 560 nm corresponding to the4G5/2→6H5/2transition of Sm3+ions. The optimum concentration of Sm3+ions in Ba2B10O17, critical transfer distance (Ra) and concentration quenching mechanism of the presented phosphor were investigated. Moreover, CIE chromaticity coordinates and color purity performance of the Ba2B10O17:Sm3+phosphor were also discussed. The present work suggests that the Ba2B10O17:Sm3+phosphor has potential as a type of yellowish-orange emitting phosphor. Copyright © 2016 John Wiley & Sons, Ltd.
