摘要：
The Eu3+/Bi3+ ion co-doped Ba3YB3O9 red phosphor was prepared by the traditional high temperature solid phase method at low temperature. The crystal structure and luminescence properties of the samples Ba3Y1-x-yB3O9: xEu3+, yBi3+ were characterized by XRD and the fluorescence spectrometer. XRD results illustrated that Ba3Y1-x-yB3O9: xEu3+, yBi3+ were pure phase crystals. The excitation and emission spectra showed that the sample could be excited by the near-ultraviolet 350-420 nm band. The strongest excitation peak was located at 393 nm. The emission spectrum showed the characteristic peak of Eu3+. The peak position of the band was at 593 nm and 613 nm, corresponding to5D0-7F1, 5D0-7F2 feature transition. The doping concentration corresponding to the strongest emission was 0.12 mol. The CIE coordinate of the concentration of Ba3Y0.87B3O9: 0.12Eu3+, 0.01Bi3+is (0.643, 0.356) which was closest to red, and excellent color rendering was obtained. The sample Ba3Y1-x-yB3O9: xEu3+, yBi3+ phosphor was red phosphor for near-ultraviolet excitation trichromatic white LED with potential application. © 2020, Materials Review Magazine.
