Research Abstract

We fabricated nano-structured glass ceramics by using nano-second pulsed laser with space selective irradiation, as a spatiotemporal modification of glass crystallization. Crystallized glass composed with Pt-TiO_2 nano-particles, useful for enhanced photo-generated catalysis, was realized.
