摘　　要：The potassium terbium polyphosphate crystal KTb（PO3）4 has been synthesized using a high temperature solution reaction method. The structure and composition were characterized by single-crystal X-ray diffraction, powder X-ray diffraction and elemental analysis. The compound crystallizes in the monoclinic space group P21/n with a=10.3182（6）, b=8.9129（5）, c=10.7940（6） , β=105.993（1）o, V=954.3 3, Z=4, Mr=513.91, Dc=3.577 g/cm3, μ=8.585 mm（-1）, F（000）=960, S=0.955,（Δρ）max=1.380,（Δρ）min=–3.428 e/3, the final R=0.0301 and w R=0.0400 for 2301 observed reflections with I 〉 2σ（I）. In addition, pure powder of isostructural Rb Tb（PO3）4 was synthesized in order to investigate the optical property. Photoluminescence measurements show that both crystals ATb（PO3）4（A=K（1）, Rb（2）） are promising candidates to become solid-state visible green light-emitting sources.The potassium terbium polyphosphate crystal KTb（PO3）4 has been synthesized using a high temperature solution reaction method.
