【 摘 要 】
In order to investigate the luminescence properties of Ba3Y(PO4)3 doped with rare earth ions, a series of Eu3+ and Dy3+ single doped Ba3Y(PO4)3 phosphor powders were prepared by high temperature solid phase method. The relevant performance of samples were characterized by X ray diffraction (XRD) and fluorescence spectra. The results showed that the prepared phosphor was a cubic phase of bismuth ore and the space group is I-43d. Under the excitation of near violet light, the narrow band emission of Ba3Y(PO4)3:0.08Eu3+ was nearly located at 594nm, 613nm and 702nm, which showed orange red light emission. The Ba3Y(PO4)3:0.08Dy3+ narrow band emission was located at 485nm and 575nm respectively, which showed white light emission. The matrix material was doped with a single active ion, and the white light emission was achieved through its coordination in different light regions. The characteristic emission peak of Eu3+ in the red light region (580∼650nm, 5D0-7FJ) could compensate for the lack of red components in the Dy3+ white light emission spectrum, thus the quality of white light of the single doped Dy3+phosphor could be improved, and it was expected to be applied to light-emitting diode (LED) field.
