| Research Abstract |
We have developed a new technique of submicron spheres fabrication by pulsed laser melting in liquid. In this technique, raw particles dispersed in liquid medium are irradiated by pulsed laser with adequate fluence, resulting in spherical particle formation via droplets generated by raw particle melting. In this program, we attempt a particle size control of TiO_2and ZnO by this technique and an optical application of these particles.
