Borate-phosphates exhibit a wide range of compositional and structural diversity, making them ideal hosts for luminescent materials. In this work, a new borate-phosphate compound CsNa 2 Dy 2 (BO 3 )(PO 4 ) 2  has been prepared under high temperature solution growth method. It crystallizes in an orthorhombic space group  Cmcm  with the following lattice parameters determined by single-crystal X-ray diffraction:  a  = 6.9709(5),  b  = 14.9699(11),  c  = 10.6480(8) Å,  z  = 4. Its structure contains isolated BO 3  planar triangles and PO 4  tetrahedra, which are interconnected by Cs + , Na +  and Dy 3+  ions. Solid solutions of CsNa 2 Y 2(1− x ) Dy 2 x  (BO 3 )(PO 4 ) 2  ( x  = 0 − 0.08) are prepared and exhibit a yellow emissive luminescence by near-UV excitation due to the  4 F 9/2  →  6 H (13/2, 15/2)  transitions of Dy 3+ . The optimized concentration of Dy 3+  is  x  = 0.01, and if over this critical value, the luminescent intensity will decrease due to concentration quenching. The Commission International de L’Eclairage (CIE) coordinates for CsNa 2 Y 1.98 Dy 0.02 (BO 3 )(PO 4 ) 2  are ( x  = 0.377,  y  = 0.404), corresponding to yellow color. The prepared phosphor may serve as a yellow phosphor for NUV-excited LEDs.
