Research Abstract	We developed novel plasmonic materials, which were made of metal nanoparticles covered with liquid-crystal molecules. The results of the study can be classified into two parts :(1) Complex of columnar liquid crystals and gold nanoparticles, and(2) Complex of calamitic liquid crystals and gold nanoparticles. Study 1 aimed at the application to a random laser. With metal nanoparticles added, we have observed the random lasing properties induced by localized surface plasmons. Study 2 aimed at the spontaneous formation of the three-dimensional structure of the metal particles. The synthesized complex showed the columnar phase with a cubic structure.
