Abstract

The present invention provides a method for manufacturing silver triangular pyramid particles including: forming an electric field in an electrolytic solution including silver ions and a surfactant to reduce the silver ions into silver triangular pyramid particles.

Claims

exact text as granted — not AI-modified
1 . A method for manufacturing silver triangular pyramid particles comprising: forming an electric field in an electrolytic solution including silver ions and a surfactant to reduce the silver ions into silver triangular pyramid particles. 
   
   
       2 . The method according to  claim 1 , wherein the surfactant has an alkyl chain with 1 to 20 carbon atoms. 
   
   
       3 . The method according to  claim 1 , wherein the amount of the surfactant is 1 to 10,000 parts by weight relative to 100 parts by weight of the silver ions in the electrolytic solution. 
   
   
       4 . The method according to  claim 2 , wherein the amount of the surfactant is 1 to 10,000 parts by weight relative to 100 parts by weight of the silver ions in the electrolytic solution. 
   
   
       5 . The method according to  claim 1 , wherein the silver triangular pyramid particles have a surface plasmon absorption peak in a visible light region. 
   
   
       6 . The method according to  claim 2 , wherein the silver triangular pyramid particles have a surface plasmon absorption peak in a visible light region. 
   
   
       7 . The method according to  claim 3 , wherein the silver triangular pyramid particles have a surface plasmon absorption peak in a visible light region. 
   
   
       8 . The method according to  claim 4 , wherein the silver triangular pyramid particles have a surface plasmon absorption peak in a visible light region. 
   
   
       9 . A silver particle having a triangular pyramid shape. 
   
   
       10 . The silver particle according to  claim 9 , wherein the silver particle has a surface plasmon absorption peak in a visible light region.
