Among the various luminescent material series, lanthanide coordination polymer crystals have attracted attention for their characteristic photophysical properties based on the arrangement of lanthanide ions and organic linker ligands. Here, we demonstrate the morphology controllability of the thermostable crystalline europium coordination polymer [Eu(hfa)3dpbp]n, [hfa: hexafluoro-acetylacetonate; dpbp: 4,4’-bis(diphenylphosphoryl) biphenyl] to realize transparent phosphors. The obtained spherical Eu3+-coordination particles were characterized using X-ray diffraction, scanning electron microscopy, dynamic light scattering measurements, and thermogravimetric analysis. The knowledge obtained is expected to be widely used as a transparent material development technique for new lanthanide-based coordination phosphors.
