Low-temperature luminescence and phase structure of 5CB liquid crystal under different cooling regimes
The 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 150deg/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.
