Four kinds of morphologies of Eu3+ doped indium borate of the InBO3 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 InBO3:Eu3+ samples have been investigated by photoluminescence (PL) spectra. The results show that the fluorescence performance is strongly correlated with morphologies. The prepared InBO3:Eu3+ phosphors show strong orange emissions under ultraviolet excitation at 237 nm, in which the monodisperse octahedra sample prepared with K2B4O7 center dot 4H(2)O as the boron source and Eu3+ doping concentration being 5% possesses the higher PL intensity and color purity, which can be used as a potential orange luminescent material.
