Optical Radiative Properties of Eu3+-doped Polymer Optical Fiber

制备了掺铕螯合物的阶跃型聚合物光纤.根据Judd-Ofelt (J-O) 理论,从铕螯合物Eu(DBM)3掺杂的聚甲基丙烯酸甲酯(PMMA)的发射光谱获得了光学跃迁的J-O参数Ω2、Ω4(Ω2=15.71×10-20cm2,Ω4=0.24×10-20cm2).用J-O参数计算了铕离子激发态(5D0)的辐射跃迁几率(513.97s-1)和辐射寿命(1945.6μs),同时计算了5D0→7FJ跃迁的受激发射截面σij和荧光分支比β,分析表明,Eu(DBM)3掺杂的PMMA可望用于聚合物光纤放大器和激光器.
