LuFeO3particles were synthesized via a hydrothermal route, where the influence of various experimental parameters on the products was systematically investigated. XRD analysis reveals that single o-LuFeO3samples can be synthesized at reaction temperatures of 160–260 °C, reaction times of 24–60 h, NaOH concentrations of 0.625–6.25 M, and Lu3+/Fe3+ion concentrations of 0.025–0.075 M. SEM observation shows that LuFeO3particles prepared at relatively low temperatures (160–220 °C) and low NaOH concentrations (0.625–3.75 M) exhibit bar-like shape, and the aspect ratio of the bars decreases with increasing the temperature and NaOH concentration. At relatively high temperatures (240–260 °C) and high NaOH concentrations (5–6.25 M), the resulted LuFeO3particles are shaped like spheres, polyhedrons or cubes. The samples prepared at the temperature of 220 °C and the NaOH concentration of 2.5–3.75 M have a relatively large particle size. All the particles exhibit a layered structure, indicating that they are mainly constructed from irregular sheets. Compared to the reaction temperature and NaOH concentration, the reaction time and Lu3+/Fe3+concentration has a relatively small effect on the morphology and size of LuFeO3particles. The as-prepared LuFeO3samples have a similar bandgap energy of 2.14 eV and exhibit a week ferromagnetic behavior at room temperature.
