Abstract

Stochastic models to describe the inhomogeneous broadening of electronic transitions of dye molecules in amorphous hosts [1] and to account for the effects of external hydrostatic pressure on spectral holes [2] have been applied to analyze experimental results obtained in a variety of samples, with hosts ranging from polymers to aerogels. With these models it was possible to determine the compressibilities of various polymers by purely optical experiments. It is interesting that these results are in agreement with mechanically obtained data within approx. 15%. Furthermore, the depth ϵ of the assumed Lennard-Jones dye-matrix interaction potential could be calculated.
通过烧孔实验分析染料掺杂稀有气体基质中基质相关性的重要性
描述染料分子在非晶载体中电子跃迁的非均匀展宽的随机模型[1]和考虑外部静水压力对光谱空穴的影响的随机模型[2]已被应用于分析从聚合物到气凝胶的各种样品中获得的实验结果。有了这些模型,就有可能通过纯光学实验来确定各种聚合物的可压缩性。有趣的是,这些结果与机械获得的数据在大约。15%。此外,可以计算假设Lennard-Jones染料-矩阵相互作用势的深度ε。
