Spectral hole burning in glasses and polymer films: the Stark effect

摘要: The influence of an externally applied electric field on spectral holes burned in the inhomogeneously broadened absorption bands OEP (octaethylporphyrin) and chlorin (2,3-dihydroporphyrin) a PVB (poly(vinyl butyral)) matrix at 1.7 K is presented. For both molecules linear Stark effect observed. In case OEP, caused by interaction matrix-induced dipole moments field. results from molecular as well moments. analysis experimental data based theory which involves moments, polarizabilities, transition guest molecules, guest-host interaction, macroscopic parameters experiment.
