| Outline of Final Research Achievements |
Laser melting in liquids attracts much attention as a novel technique to prepare spherical particles of sub-micron size. In this research, we have applied this technique to prepare gold sub-micron particles (AuSMP) and investigated the formation mechanism. As a result of the investigation, we have clarified following things.
1) The agglomeration of the source gold nanoparticles is necessary to obtain AuSMP. 2) When stabilizing reagent is used, the agglomeration is induced by laser irradiation dynamically. 3) As the stabilizing reagents, inorganic salts such as NaCl can be used as well as the ordinary stabilizing reagents such as sodium citrate. 4) The stabilizing reagents influence on the agglomeration process and AuSMP size.
