Nanocarbon-producing device

Abstract

In a nanocarbon-producing device ( 173 ), a plane mirror ( 169 ) and a parabolic mirror ( 171 ) are arranged in a production chamber ( 107 ). Light, emitted from a laser light source ( 111 ), transmitted through a ZnSe window ( 133 ) is reflected at the plane mirror ( 169 ) and the parabolic mirror ( 171 ), collected at the parabolic mirror ( 171 ), and then irradiated onto the surface of a graphite rod ( 101 ).

1 . A nanocarbon producing apparatus comprising: 
 a graphite target;    a chamber which accommodates said graphite target;    a window unit which is provided in a part of said chamber;    a light source which irradiates light onto a surface of said graphite target through said window unit;    a recovery unit which recovers a nanocarbon generated from carbon vapor, said carbon vapor being vaporized from said graphite target by said light irradiation; and    a shielding member which is located between said window unit and said graphite target.    
     
     
         2 . The nanocarbon producing apparatus as claimed in  claim 1 , comprising an optical member between said window unit and said shielding member, said optical member introducing said light to said surface of said graphite target.  
     
     
         3 . The nanocarbon producing apparatus as claimed in  claim 1 , wherein said optical member includes a reflecting member.  
     
     
         4 . A nanocarbon producing apparatus comprising: 
 a graphite target;    a chamber which accommodates said graphite target;    a window unit which is provided in a part of said chamber;    a light source which irradiates light onto a surface of said graphite target through said window unit;    a recovery unit which recovers a nanocarbon generated from carbon vapor, said carbon vapor being vaporized from said graphite target by said light irradiation; and    a reflecting member which reflects transmitted light transmitted through said window to introduce the transmitted light to said surface of said graphite target.    
     
     
         5 . The nanocarbon producing apparatus as claimed in  claim 4 , further comprising a shielding member located between said reflecting member and said graphite target.  
     
     
         6 . The nanocarbon producing apparatus as claimed in  claim 3 , wherein said reflecting member has a light focusing function.  
     
     
         7 . The nanocarbon producing apparatus as claimed in  claim 3 , wherein said reflecting member is a parabolic mirror.  
     
     
         8 . The nanocarbon producing apparatus as claimed in  claim 1 , comprising target holding unit which rotates said graphite target having a cylindrical shape around an central axis while holding the graphite target.  
     
     
         9 . The nanocarbon producing apparatus as claimed in  claim 1 , wherein said nanocarbon is a carbon nanohorn assembly.  
     
     
         10 . The nanocarbon producing apparatus as claimed in  claim 2 , wherein said optical member includes a reflecting member.  
     
     
         11 . The nanocarbon producing apparatus as claimed in  claim 4 , wherein said reflecting member has a light focusing function.  
     
     
         12 . The nanocarbon producing apparatus as claimed in  claim 5 , wherein said reflecting member has a light focusing function.  
     
     
         13 . The nanocarbon producing apparatus as claimed in  claim 4 , wherein said reflecting member is a parabolic mirror.  
     
     
         14 . The nanocarbon producing apparatus as claimed in  claim 5 , wherein said reflecting member is a parabolic mirror.  
     
     
         15 . The nanocarbon producing apparatus as claimed in  claim 6 , wherein said reflecting member is a parabolic mirror.  
     
     
         16 . The nanocarbon producing apparatus as claimed in  claim 2 , comprising target holding unit which rotates said graphite target having a cylindrical shape around an central axis while holding the graphite target.  
     
     
         17 . The nanocarbon producing apparatus as claimed in  claim 3 , comprising target holding unit which rotates said graphite target having a cylindrical shape around an central axis while holding the graphite target.  
     
     
         18 . The nanocarbon producing apparatus as claimed in  claim 4 , comprising target holding unit which rotates said graphite target having a cylindrical shape around an central axis while holding the graphite target.
