METHOD FOR PRODUCING GOLD PARTICLE, GOLD PARTICLE, LASER ABLATION APPARATUS, COLLECTING MEMBER USED THEREFOR AND METHOD FOR PRODUCING PARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a method for producing gold particles by which a large number of large gold particles having a particle size of ≥350 nm are generated.;SOLUTION: A target made of gold is arranged in a chamber of a laser ablation apparatus. Then, supercritical trifluoromethane having a reduced-density of ≥0.7 is stored in the chamber. Thereafter, the target is irradiated with laser beam to generate gold particles made of the target through laser ablation. A large number of large gold particles can be generated by selecting trifluoromethane as the supercritical fluid, and setting the reduced-density of the supercritical fluid to be ≥0.7.;COPYRIGHT: (C)2011,JPO&INPIT
