- Аннотация: We report complex optical investigations of polymer-stabilised cholesteric photonic liquid crystaldoped by a dichroic fluorescent dye. For the first time, we employed a combination of variousexperimental methods, including measurements of spectra of transmission, reflection, rotation of theplane of polarisation of light, fluorescence, to characterise the properties of the photonic crystal. Thepeculiarity of the reported investigations is employing a photosensitive cholesteric mixture forming thephotonic crystal. The position of the photonic band could be changed by illumination with ultravioletlight and stabilised by thermopolymerisation. In this way, the position of the cholesteric band wasmatched with the emission band of the fluorescent dye, which enabled to perform diversified studieson the same photonic crystal. We determined the parameters, which defined the optical properties ofthe photonic crystal, spectral dependence of the transformation of linearly polarised light to ellipticallypolarised as the light passes the photonic crystal, the photonic density of states. The interpretation ofthe experimental data was performed using analytical expressions obtained from the solution ofMaxwell’s equations, numerical calculations by the Berreman matrix method.
