“…An efficient way to construct a white LED is to combine a UVemitting chip with three different phosphors. Therefore, new explorations of single host phosphors excited by UV or near UV (NUV) light have attracted much attention because of high efficiency, good colour rendering index and stable colour tone (Vijayakumar & Huang, 2018;Litterscheid et al, 2016). One kind of host matrix, phosphate compounds, have received much attention recently due to advantageous positive factors, including simple preparation methods, structural diversity, high chemical stability and suitable band gap.…”

For the first time, a new langbeinite‐type phosphate, namely potassium terbium tantalum tris(phosphate), K2Tb1.5Ta0.5(PO4)3, has been prepared successfully using a high‐temperature flux method and has been structurally characterized by single‐crystal X‐ray diffraction. The results show that its structure can be described as a three‐dimensional open framework of [Tb1.5Ta0.5(PO4)3]∞ interconnected by K+ ions. The TbIII and TaV cations in the structure are disordered and occupy the same crystallographic sites. The IR spectrum, the UV–Vis spectrum, the morphology and the Eu3+‐activated photoluminescence spectroscopic properties were studied. A series of Eu3+‐doped phosphors, i.e. K2Tb1.5–xTa0.5(PO4)3:xEu3+ (x = 0.01, 0.03, 0.05, 0.07, 0.10), were prepared via a solid‐state reaction and the photoluminescence properties were studied. The results show that under near‐UV excitation, the luminescence colour can be tuned from green through yellow to red by simply adjusting the Eu3+ concentration from 0 to 0.1, because of the efficient Tb3+→Eu3+ energy‐transfer mechanism.
