| 摘要: 以P123为表面活性剂，异丙醇铝为铝源，用简易溶胶-凝胶法，获得了单掺和双掺Gd3+，Eu3+的介孔氧化铝组装体。用广角X-射线衍射仪(WAXD)进行了物相分析；小角X-射线衍射仪(SAXD)、比表面仪进行了孔结构分析和形貌表征；研究了组装体的发光性能并发现Gd3+对Eu3+有能量传递作用，并分析了能量传递过程。 |

| Abstract: Employing P123 as a structure-directing agent and aluminium isopropoxide as alumina source, Gd3+ or Eu3+ doped mesoporous alumina and co-doped mesoporous alumina were fabricated by simple sol-gel method. The product was characterized by WAXD, SAXD, and N2 adsorptiondesorption isotherms. The luminescent properties of doped-MA were studied and energy transfer from Gd3+ to Eu3+ in ordered mesoporous alumina was observed. The energy transfer process was discussed. |
