Method for producing a dielectric matrix composites containing metal and/or semiconductor nanoparticles, in the form of rods having the plasmonic properties

摘要

The object of the invention is a method of producing composites with a dielectric matrix comprising metallic and/or semi-conductive nanoparticles in the form of rods with plasmonic properties, which are used especially in plasmonics and optoelectronics, comprising metallic and/or semi-conductive nanoparticles in their volume. The method according to the invention consists in that a dielectric input material is milled into the form of a fine crystalline granulate, which is thoroughly mixed with nanoparticles of at least one metal and/or semi-conductive compound having the melting point higher than the melting point of the matrix, and then the thus-produced matrix with nanoparticles uniformly distributed throughout its volume is melted at a temperature lower than the melting point of the nanoparticles in a crucible (1) of a system for micro-pulling down from the melt, after which said matrix undergoes the process of gravitational micro-pulling down.
