Provided are a photonic crystal ink composition for inkjet printing, which satisfies physical properties of nano particles for forming a 3-dimensional photonic crystal pattern, and a method for forming 3-dimensional photonic crystal by inkjet printing. The photonic crystal ink composition for inkjet printing comprises: monodispersed nano particles; a main solvent; a wetting agent for preventing clogging at a nozzle part of an inkjet printer; and a surface tension control agent. The composition satisfies the viscosity condition of 0.5-40mPaÀs, a Newtonian flow behavior condition, and a surface tension condition of 20-70mN/m. The monodispersed nano particles are spherical particles of metal oxide, semiconducting inorganic particles, or polymer latex beads. |
