| Abstract: | AbstractThe effects of the 5CB liquid crystal (LC) cooling regimes on its luminescence spectra at the low temperature (T?=?4.2 K) have been found out and investigated. Experiments have been carried out at two cooling rates: 2 and 150?deg/min. Differential scanning calorimetry (DSC) data allow us to establish that the 5CB glass-like state (GLS) is formed during the rapid cooling of the sample. Peculiarities of the LC dimer formation under the different cooling conditions are discussed. |
