We prepared gold nanoparticles-embedded titanosilicate crystal, on which plasmon-enhanced visible light response was expected. At first, we prepared a typical titanosilicate, ETS-10 crystal, whose size was varied from 1 to 5μm by changing the boiling time of the materials gel. By adding gold nanoparticles(3 nm dia.) in the ETS-10 preparation process, we successfully obtained pink-colored titanosilicate crystal, indicating wide dispersion of gold nanoparticles in the crystal. In the
