The effect of a dc electric field on persistent spectral holes in the absorption spectra of perylene doped polyvinyl butyral films has been measured. This effect is not like a typical Stark effect that is obtained with polymer films doped with polar dye molecules. Instead, a new phenomenon of reversible spectral hole filling is observed. This phenomenon is attributed to the elastic deformation of the interaction potentials of the dopant and the polymer associated with reversible field-induced tunneling in the intrinsic two-level systems. A quantitative theory of the phenomenon is proposed.
