Monodispersed LaCO3OH microgears with a novel plum blossom-like structure are prepared by a simple, reliable, environmentally-friendly and glycerol-mediated solvothermal method for the first time. By studying the effect of the experimental parameters on the morphology of LaCO3OH structures, we find that urea and glycerol at high concentration play a significant role in the formation of the plum blossomlike LaCO3OH microgears. In addition, we observe that the morphology evolution of the LaCO3OH microgears is from wires, spheres composed of rods, to plum blossom-like products with the increase of reaction time. More importantly, PL results demonstrate that the LaCO3OH microgears show a stronger PL than that of other structures, such as wires and spheres.
