| Research Abstract |
In this project, we have studied the improvement of optical properties of nanoparticles by the irradiation of laser and their applications. We have obtained the following results.
(1) The mechanism of increase in fluorescence intensity of ZnO nanoparticles by the irradiation of laser was that the passivation of surface defects on ZnO nanoparticles by highly crystalline ZnO layer which was synthesized photochemically with the irradiation of laser increased fluorescence intensity.
(2) The optical properties of various nanoparticles were improved by the surface passivation.
(3) The rapid preparation of highly functionalized nanoparticles which was important for engineering applications was successfully done.
