METHOD OF PRODUCING METAL FINE PARTICULATE LAYER

PROBLEM TO BE SOLVED: To produce a metal particulate layer having uniform thickness used, e.g., for a sensor with localized plasmon resonance applied. SOLUTION: A substrate 1 composed of porous alumina in which a plurality of micropores 12a are formed by anodization, is used to fill a plurality of m...

Summary:PROBLEM TO BE SOLVED: To produce a metal particulate layer having uniform thickness used, e.g., for a sensor with localized plasmon resonance applied. SOLUTION: A substrate 1 composed of porous alumina in which a plurality of micropores 12a are formed by anodization, is used to fill a plurality of metal colloid particles 13 into each micropore 12a in the substrate 12 by coating, and thereafter, the metal colloid particles 13 are heated, thus organic molecules 13b are volatilized, and, further, the metal particulates 13a are dissolved. Subsequently, the temperature is reduced to a room temperature to resolidify the metal, thus metal particulates 16 in which the diameter h in the depth direction of each micropore 12a is uniform are produced. In this way, a uniform metal particulate layer 17 having thickness h is obtained. COPYRIGHT: (C)2005,JPO&NCIPI
