MULTI-METALLIC NANOPARTICLES STRUCTURE AND METHOD FOR FABRICATING THE SAME AND PHOTO DEVICE INTEGRATED WITH MULTI-METALLIC NANOPARTICLES AND METHOD FOR FABRICATING THE SAME

摘要

The present invention relates to a multi- structure and a method for manufacturing metal nanoparticles , on a substrate , at least two different metal material , followed by heat treatment at different temperature conditions, the first and second metal nanoparticles is formed , wherein the first metal nanoparticles are formed by crystallization of the first metal film deposited on the substrate by a first heat treatment , whereby the second metal nanoparticles are formed by crystallizing the second metal film deposited on a substrate including the first metal nanoparticles by a second heat treatment , than the effects that can absorb more light in a wide wavelength there . ;
