Abstract

A anhydrous orthoborate Na₃Tb(PO₄)₂ has been prepared and its crystal structure was determined by X-Ray diffraction of a non-merohedral twinned single crystal. The results show that the compound crystallizes in monoclinic space group C2/c and the structure features a 3D framework containing PO₄, NaO₆, NaO₇, NaO₈ and TbO₈ polyhedra. Under near-UV excitation (370 nm), Na₃Tb(PO₄)₂ shows intense characteristic emission bands of Tb³⁺ (490 nm, 543 nm, 585 nm and 620 nm) with the CIE coordinate of (0.3062, 0.5901), corresponding to greenish color. The excitation spectrum covers a wide range from 340 nm to 390 nm, which indicates that phosphor Na₃Tb(PO₄)₂ can be efficiently activated by near-UV LED ship.
