BiNbO<SUB>4</SUB>:RE<SUP>3+</SUP> (RE = Dy, Eu, Sm, Tb) phosphors were prepared by solid-state reaction at 1100℃ and their structural, photoluminescent, and morphological properties were investigated. XRD patterns exhibited that all the synthesized phosphors exhibited a triclinic system with a dominant (210) diffraction peak, irrespective of the type of activator ions. The surface morphologies of rare-earth-ion-doped BiNbO<SUB>4</SUB> phosphors were found to depend strongly on the type of activator ions. The Eu<SUP>3+</SUP> and Dy<SUP>3+</SUP> doped BiNbO4 phosphors revealed a strong red (613 nm) emission resulting from the <SUP>5</SUP>D<SUB>0</SUB>→<SUP>7</SUP>F<SUB>2</SUB> transition of Eu<SUP>3+</SUP> and a dominant yellow (575 nm) emission originating from the <SUP>4</SUP>F<SUB>9/2</SUB>→<SUP>6</SUP>H<SUB>13/2</SUB> transition of Dy<SUP>3+</SUP>, respectively, which were the electric dipole transitions, indicating that the activator ions occupy sites of non-inversion symmetry in the BiNbO<SUB>4</SUB> phosphor. The main reddish-orange emission spectra of Sm<SUP>3+</SUP>-doped BiNbO<SUB>4</SUB> phosphors were due to the <SUP>4</SUP>G<SUB>5/2</SUB>→<SUP>6</SUP>H<SUB>7/2</SUB> (607 nm) magnetic dipole transition, indicating that the Sm<SUP>3+</SUP> ions were located at inversion symmetry sites in the BiNbO<SUB>4</SUB> host lattice. As for Tb<SUP>3+</SUP>-doped phosphors, green emission was obtained under excitation at 353 nm and its CIE chromaticity coordinates were (0.274, 0.376). These results suggest that multicolor emission can be achieved by changing the type of activator ions incorporated into the BiNbO<SUB>4</SUB> host crystal.
