本文通过建立不同浓度五磷酸盐非晶材料(ErxLa1-xP5O14)动力学过程的速率方程,特别是引入了改进系数exp{hcv珋k/kT}以区别能量传递Stokes过程和反Stokes过程,分别对Er0.01La0.99P5O14,Er0.1La0.9P5O14,和ErP5O14非晶材料中979.3nm,803.8nm和521.8nm光激发下所有能级的动力学过程在改进能量传递理论前后进行了比较,结果发现,当稀土离子间距较小时(如在ErP5O14非晶中),考虑能量传递Stokes和反Stokes过程差别对计算模拟非常重要,说明此时能量传递起到了关键性作用.而离子间距较大时,则几乎无影响.并且发现全浓度ErP5O14非晶材料在可见光激发下存在红外量子剪裁现象.且详细计算了有关的无辐射弛豫速率、自发辐射速率和能量传递速率,分析了有关的能量传递动力学过程,发现速率为239500s-1的{2.11/2→4I9/2,4I15/2→4I13/2}交叉能量传递是导致光激发2.11/2能级的红外量子剪裁现象的主要原因,该研究对于寻找高效率的太阳能电池材料很有意义.

结合理论分析与实验测试,研究了在可见光脉冲输入条件下频率以及第二片微通道板与阳极之间电势差对微通道板光电倍增管动态范围的影响。研究结果表明:随着信号光脉冲频率的增大,微通道板壁面电荷补充不充分致使阳极输出偏离线性,并逐渐趋于饱和。当输入可见光脉冲宽度为50 ns,频率为500 Hz时,阳极的最大线性输出达到2 V(即40 mA);当输入光频率增加到1000 Hz,阳极输出在1 V(即20 mA)时线性偏离程度达到10%以上;当输入光频率增加到5000 Hz,阳极输出在0.3 V(即6 mA)时线性偏离程度达到约15%。随着第二片微通道板与阳极之间电势差的增大,阳极最大线性输出电压呈现波动性变化而非与其呈线性关系。当第二片微通道板与阳极之间的电势差在200 V左右时,阳极线性输出电压达到峰值,随着电势差不断增大,阳极线性输出电压开始出现波动,在电势差为500 V左右时达到第二个峰值,这主要是由于极板间电场强度与空间电荷效应共同作用的结果。该研究可为提升微通道板光电倍增管的动态范围提供指导,便于其应用于强辐射脉冲测量、激光通信等领域。
