摘要： PROBLEM TO BE SOLVED: To provide a technology by which functional oxide nanoparticles having a uniform particle diameter can be easily synthesized.
SOLUTION: The nanoparticle synthessis apparatus 1 is equipped with an ultraviolet laser beam source 2, a laser beam reflection mirror 3, a reaction vessel 4, and a solvent solution 5 of a metal salt charged into the reaction vessel 4. In the reaction vessel 4, a solution obtained by dissolving the metal salt into a solvent is stored. The suitability of the solvent depends on the absorption performance in an ultraviolet region. An alcohol is not required as a solvent for cerium nitrate. An alcohol solvent is however required depending on the kinds of salts (e.g., iron-based salt). Fig.4 shows the results obtained by calculating the dependency of the particle diameter, the lattice constant, obtained by using X-ray diffraction pattern, and the yield of cerium oxide on laser output. From the Fig.4, it is found that cerium oxide nanoparticles having an average diameter of 2 nm are synthesized and the yield of the nanoparticles is increased as the laser output is increased while maintaining the particle diameter, and further, the lattice constant and the particle diameter hardly depend on the output and are kept constant.
