采用传统的固相凝固法合成了Eu3+掺杂的YBa3B9O18。(Y1-xEux)Ba3B9O18在x=0-1.0范围内形成固溶体。在紫外可见光范围内的激发发光性质测量表明，Eu3+的激发和发射是众所周知的。Eu3+的电荷转移激发带在激发光谱中占主导地位。由于Eu3+离子的D-5(0)能级跃迁到F-7(J)(J=0，1，2，3，4)能级跃迁，Eu3+离子的发射光谱主要由550-720 nm范围内的几组谱线组成。EuBa3B9O18的发光强度与Eu3+浓度的依赖关系表明，完全浓度的EuBa3B9O18没有浓度猝灭。掺Eu3+的YBa3B9O18是一种在显示器和光学器件中有应用前景的荧光粉。(C)2012爱思唯尔B.V.保留所有权利。
Europium (Eu3+) doped YBa3B9O18 were synthesized by conventional solid state solidification methods. (Y1-xEux)Ba3B9O18 formed solid solutions in the range of x=0-1.0. The luminescence property measurements upon excitation in ultraviolet-visible range show well-known Eu3+ excitation and emission. The charge transfer excitation band of Eu3+ dominates the excitation spectra. The emission spectrum of Eu3+ ions consists mainly of several groups of lines in the 550-720 nm region, due to the transitions from the D-5(0) level to the levels F-7(J) (J=0, 1, 2, 3, 4) of Eu3+ ions. The dependence of luminescence intensity on Eu3+ concentration shows no concentration quenching for fully concentrated EuBa3B9O18. Eu3+ doped YBa3B9O18 are promising phosphors for applications in displays and optical devices. (C) 2012 Elsevier B.V. All rights reserved.
