| Abstract: | A principal role of the nanocrystallites of La2CaB10O19 on single pulse photoinduced changes of the liquid crystals was shown. It was established that the effect of the photoinduced changes is sensitive to the concentration of the nanocrystallites and to the type of liquid crystalline matrices. The principal role in the observed effects should play local thermoheating which determines effective exchange of energy between the nanocrystallites and the polymer matrices. |
