Light- and Thermoinduced Spectral Diffusion in Organic Amorphous Systems Measured via Hole Burning Stark Spectroscopy,
Abstract
Spectral diffusion (SD) is extensively investigated in the past years by means of hole burning method. In particular, evidences of thermo- and light-induced SD are found. At the same time authors have found a strong dependence of the burned hole width on the burning fluence. As known, the classical model of a burning kinetics (hole broadening in this model is connected with saturation of the hole in the distribution function of impurity centers) predicts enough weak hole broadening at the initial stage of burning. It leads to a conclusion about possible additional mechanisms of hole broadening on an initial burning stage. One of such mechanisms can be SD, induced by the burning light (LISD).
