Abstract

The structural photomodification of the multicomponent cyanine films was studied. The spectrum of the film shows different bands of components, formed by dye molecules. Optical properties of the films were determined by the relative concentrations of the molecular forms and their orientation angles. Laser-induced changes in the absorption spectra of film associated with the variation of the relative concentrations of the forms and their orientation angles. The dependence of angle on the total photoexcitation energy had the form of saturating functions. Maximum limiting angles depend on the initial orientation angles of the component.
