Abstract: YBO3∶Eu3+ microspheres with flower-like structures were fabricated by a facile hydrothermal method. The composition, structure and morphology of obtained YBO3∶Eu3+ were studied by means of XRD、EDX, HRTEM and SEM. The as-prepared YBO3∶Eu3+ microspheres show hexagonal vaterite phase with the elements of Y, O, B, Eu to be found. The YBO3 microspheres, with an average diameter of 1-2μm, are composed of nanosheets with thickness of 100nm. The formation mechanism of the flower-like structures is also proposed. The YBO3∶Eu3+ samples have a strong red emission at 612nm and a high R/O ratio under ultraviolet excitation, which indicate lower symmetry of crystal field around Eu3+ in such flower-like structures.

Key words: hydrothermal synthesis, YBO3∶Eu3+, photoluminescence, flower-like structure
