摘要：

Rare earth borogermanates as a group of stable compounds provided various potential properties important for modern sciences. Among the properties of interests, luminescence was manifested due to the variability of rare earth elements and the compounds constituted an important group of potential candidate. In this work, novel phosphors of Eu3+, Tb3+ or Tm3+ doped LaBGeO5 with the stillwellite type structure were synthesized by the solid state reaction method. Their X-ray and UV excitation luminescent properties showed that LaBGeO5 was an excellent host lattice for the luminescence of Eu3+, Tb3+ and Tm3+. The LaBGeO5:Eu3+, LaBGeO5:Tb3+ and LaBGeO5:Tm3+ presented bright red, green and blue emission light for both UV and X-ray excitation.
