ELECTRODE MATERIAL, ELECTRODE, AND COLD CATHODE FLUORESCENT LAMP

摘要

<P>PROBLEM TO BE SOLVED: To provide an electrode material and an electrode which improve luminance of a cold cathode fluorescent lamp and to provide a cold cathode fluorescent lamp having a high luminance. Ž<P>SOLUTION: The electrode material is used for an electrode of a cold cathode fluorescent lamp and is made of nickel or nickel alloy having an excellent plasticity processability, and a mean crystal particle diameter is 50 μm or less and a surface roughness Sm is 50 μm or less. The electrode material of which the surface has a fine concavo-convex shape and is made of fine structures has a work function less than 4.7 eV and an etching rate less than 22 nm/min. The electrode made of the above electrode material has an improved discharge property and a spattering resistance and improves luminance of the cold cathode fluorescent lamp.
