A new melilite-type rare-earth borate CdTbGaB₂O₇ and multicolor tunable emission in the CdTb_1-xSm_xGaB₂O₇ (0 ≤ x ≤ 0.2) phosphors.

ABSTRACT: A new mixed metal borate, CdTbGaB₂O₇, was successfully synthesized using the high-temperature solution method and its crystal structure was determined by single-crystal X-ray diffraction with the following unit-cell data: P4̄2₁m, a = b = 7.3487(1) Å, c = 4.7247(1) Å, V = 255.150(9) ų, and Z = 2. It belongs to a new member of the melilite family, which features a 3D framework consisting of alternately stacked [Ga(B₂O₇)]_n^5n- tetrahedral layers and (Cd²⁺/Tb³⁺) cationic layers that are interconnected via B(Ga)-O-(Cd/Tb) bridges. In addition, the solid solutions of CdTb_1-xSm_xGaB
