摘要
首次报道了四-对羟基苯基卟吩/有机玻璃体系(THP/PMMA)的单光子永久性光谱烧孔.研究了烧孔特性和成孔条件.测量了孔的稳定性,在液氦温度下孔的保存时间已超过几个小时.实现了孔的擦除和重复烧孔.探讨了烧孔机制,认为激光诱导质子转位变构是导致该体系永久性光谱烧孔的原因.
One-photon persistent spectral hole-burning was reported for the organic guest molecule 5, 10, 15, 20-tetra-(p-hydroxyphenyl) prorphin (THP) doped into a poly (methylmethaorylate) (PMMA) amorphous matrix at liquid helium temperature. Hole properties and conditions for hole formation were investigated. Laser induced tautomerization was believed responsible for the hole burning. Stability of the holes was demonstrated longer than hours. Hole erasing and repeatable hole burning were realized.
