N. A. Hayrapetyan

In this work we have experimentally investigated optical properties of multilayered structure, consisting of two right handed Cholesteric Liquid Crystal layers with the same pitch and Rhodamine 6G (R6G) doped polymethyl metacrylate (PMMA) thin film sandwiched between them. Particularly transmission spectrum dependence on temperature is studied. The 10 nm of CLC selective reflection band tuning is achieved. The photoluminescence of R6G is registered.
