摘要： A method of producing core/shell composite nano-particles exhibiting superior characteristics, by using as cores nano-particles heat treated in advance so as to give them a specific crystal structure in a state using a barrier layer to prevent sintering and forming shells on their surface, which eliminates hindrances to the shell forming reaction due to the phase transfer catalyst or other strongly sticky dispersant, is provided. A method of producing core/shell composite nano-particles comprising nano-sized core particles covered by shells, the method comprising dispersing core particles heat treated in advance to give them a crystal structure expressing the necessary characteristics in a first organic solvent by a first dispersant to prepare a first solution, adding a polar solvent to peel off the first dispersant from the core particles and making the nano-particles agglomerate to recover them, making the recovered core particles disperse in a second organic solvent by a second dispersant to form a second solution, and adding a precursor of the shells to the second solution and forming shells on the surfaces of the core particles.

(b) thick films deposited on a substrate, applying an annealing to crystallize with pressurization at a temperature sufficiently high to enable diffusion or fluidization of a grain boundary phase and, at the same time, low enough to prevent coarsening of the crystal grains.
