%0 Journal Article %T Thermo-Optical Generation of Particle-Like Structures in Frustrated Chiral Nematic Film %J Crystals | An Open Access Journal from MDPI %D 2019 %R https://doi.org/10.3390/cryst9110574 %X The creation of metastable particle-like structures in frustrated (unwound) chiral nematic film containing light-absorbing additive is studied. It is shown that such localized structures can be generated by the thermo-optical action of a focused laser beam or arise spontaneously at a phase transition from an isotropic to a liquid crystal state. Observed axisymmetric patterns resemble cholesteric spherulites with toroidal double-twisted director-field configuration. View Full-Tex %U https://www.mdpi.com/2073-4352/9/11/574
