Efficient and color‐tunable visible‐light emission is achieved in fluorescent dye‐doped oligo(phenylenevinylene)–silica mesostructured films through fluorescence resonance energy transfer from a blue‐light‐emitting organosilica to a yellow‐light‐emitting dye (see figure). Tuning of the composition realizes pseudo white‐light emission with a quantum yield of 67%. Utilization of both walls and pores of the mesostructured organosilicas is effective to construct highly functional systems.
