Abstract: The invention relates to the use of polymer particles for the production of photonic crystals, characterized in that the polymer particles have a wei ght average particle size of more than 600 nm and an ion group content of le ss than 0.001, preferably of less than 0.0001 mol/1 g of polymer particles a nd the polymer particles form the lattice structure of the photonic crystal without being embedded in a liquid or solid matrix.
