| Research Abstract |
This research focused on investigating the photonic properties of the three-dimensionally periodic structure spontaneously formed in liquid crystal blue phases I and II. Through careful preparation of the samples and investigation of the lasing threshold characteristics of blue phases I and II, the lasing threshold was found to be the same in the two liquid crystal phases, despite their difference in symmetry. A technique to disperse nanoparticles in liquid crystals was also developed, based on sputtering.
