In this work, we have accomplished the preparation and characterization of the optical properties of 280 nm silica nanospheres coated with a luminescent conjugated polyelectrolyte, sulfonated Polyphenylene ethynylene PPE-SO3-. The conjugated polymer is coated onto the nanospheres by the L-b-L method. Previous shell construction by means of a non-luminescent electrolytic polymer host, blended with luminescent semi-conducting nanocrystals is advanced in this work by constructing the shell from a luminescent polyelectrolyte. Furthermore, we have prepared fluorescent opal structures from these core-shell structures and investigated their optical properties.
