GdBO3:Eu vaterite type particles with fine size, plate morphology, and non-aggregation were first prepared by the mild hydrothermal method. Their characteristics were investigated and compared with those of particles prepared by solid state reactions. The result showed that the hydrothermal method appears to be applicable to prepare high quality phosphors for practical uses. This conclusion was reinforced by the existence of an important improvement in the photoluminescent performances.
