Abstract

Persistent spectral hole burning (PSHB) was performed for several porphyrin molecules imbedded in polymer hosts and rare-earth ion Sm2+ doped in BaFCl0.5Br0.5 matrix. Power saturation and broadening effects for hole depth and width were observed. The dynamical process of hole formation was measured and explanation by population rate equations was given. Quantum efficiency of photochemical hole burning was investigated. For BaFCl0.5Br0.5:Sm2+ the capacity of data storage was estimated according to the result of multiple hole burning.

一些有机和无机材料的持续光谱烧孔研究
在BaFCl0.5Br0.5基体中掺杂稀土离子Sm2+,并在聚合物基体中嵌入卟啉分子,进行了持续光谱空穴燃烧(PSHB)。观察到功率饱和效应和孔深、孔宽的展宽效应。测量了井眼形成的动力学过程,并给出了种群率方程的解释。研究了光化学孔燃烧的量子效率。对于BaFCl0.5Br0.5:Sm2+,根据多孔燃烧结果估计数据存储容量。
