摘要：
A series of Ba3Lu1 - x Ce (x) (BO3)(3) phosphors with different x value were prepared by a conventional high-temperature solid-state reaction method, and their spectroscopic characteristic were systematically investigated. The excitation and emission spectra indicate Ce3+ can occupy two different Lu lattice sites, and shows different luminescence properties. The spectroscopic characteristic of Ce(1) and Ce(2) which include Stokes shift and crystal field depression were investigated. The investigation indicates that Ba3Lu(BO3)(3): Ce-3 phosphor can have potential application in white-light emitting diodes due to the near-ultraviolet excitation band and blue light emission of Ce(2) in Ba3Lu(BO3)(3).
