Graphical abstract: Four kinds of morphologies of Eu{sup 3+} doped indium borate of InBO{sub 3} phosphors have been prepared via a facile flux method only by adjusting the kinds of reaction boron source materials[(a)B{sub 2}O{sub 3}, (b)NH{sub 4}B{sub 5}O{sub 8}·4H{sub 2}O, (c)Li{sub 2}B{sub 4}O{sub 7}, (d)K{sub 2}B{sub 4}O{sub 7}·4H{sub 2}O], in which the monodisperse octahedral sample prepared with K{sub 2}B{sub 4}O{sub 7}·4H{sub 2}O as the boron source and Eu{sup 3+} doping concentration being 5% possesses the higher PL intensity and color purity, which can be used as a potential orange luminescent material. - Highlights: • InBO{sub 3}:Eu{sup 3+} phosphor with four morphologies were prepared by adjusting the boron source. • The doping concentration also has a great influence on the morphology. • The fluorescence performance is strongly correlated with morphology. • The smooth octahedral sample possesses the higher PL intensity and color purity. • InBO{sub 3}:Eu{sup 3+} smooth octahedra can be used as a potential orange luminescent material. - Abstract: Four kinds of morphologies of Eu{sup 3+} doped indium borate of the InBO{sub 3} phosphors have been prepared via a facile flux method only by adjusting the kinds of reaction boron source materials, which have been characterized by XRD, EDS and SEM. In addition, the doping concentration also has a great influence on the morphology of samples. Furthermore, the luminescence properties of the prepared InBO{sub 3}:Eu{sup 3+} samples have been investigated by photoluminescence (PL) spectra. The results show that the fluorescence performance is strongly correlated with morphologies. The prepared InBO{sub 3}:Eu{sup 3+} phosphors show strong orange emissions under ultraviolet excitation at 237 nm, in which the monodisperse octahedra sample prepared with K{sub 2}B{sub 4}O{sub 7}·4H{sub 2}O as the boron source and Eu{sup 3+} doping concentration being 5% possesses the higher PL intensity and color purity, which can be used as a potential orange luminescent material.
