YVO4:Er3+/Yb3+ nanospindles were prepared by an ultrasonic chemistry method with the assistance of EO20PO70EO20 (P123) and were characterised by X-ray diffraction, scanning electron microscope, and transmission electron microscope. The results showed that the reaction conditions influence the size and morphology of the YVO4:Er3+/Yb3+ nanospindles. With increasing reaction time, the size and morphology of YVO4:Er3+/Yb3+ nanospindles grew. With increasing P123 concentration and ultrasonic power, the size and morphology of YVO4:Er3+/Yb3+ nanospindles become more uniform. With increasing annealing temperature, the morphology of the YVO4:Er3+/Yb3+ nanospindles became irregular. In addition, their up-conversion luminescent properties were studied under increasing ultrasonic power.
