Quantum efficiency of hole formation for persistent spectral hole-burning materials
永久性光谱烧孔(PHB) 量子效率 photochemical hole burning quantum efficiency impurity center THP/PMMA integrated absorption coefficient
摘要
分析了永久性光谱烧孔(PHB)材料成孔量子效率的测量原理,建立了相应的测试方法和装置.在液氦温度(4.2 K)下对聚合物基质PMMA(聚甲基丙烯酸甲酯)中掺杂5,10,15,20-四-对羟基苯基卟吩(THP)体系的成孔量子效率进行了测量计算.
Abstract
Theory and method for the determination of quantum efficiency for photochemical hole buring (PHB) are given in detail. For the organic impurity center tetrahydroxyphenylporphin (THP) imbedded in poly (methylmethacrylate) (PMMA) amorphous matrix, the quantum efficiency is calculated according to the parameters measured at liquid helium temperature. Integrated absorption coefficient instead of dipole moment is used in the calculation.
