Large single crystals of lanthanide hydroxides [Ln(OH) 3 (Ln = La, Pr, Nd, Sm, Eu and Tb)] up to several millimeters have been grown by using solid KOH assisted hydrothermal method. Eu(OH) 3 samples, as a representative of the Ln(OH) 3 crystals, were characterized by X‐ray diffraction (XRD), 4‐circle single‐crystal diffraction, Fourier transform infrared (FTIR) spectroscopy and X‐ray photoelectron spectroscopy (XPS). FESEM image shows hexagonal prism morphology for the Eu(OH) 3 large crystals. Research on the photoluminescence and magnetic properties of Eu(OH) 3 species was conducted.
