Periodic arrays of silver nanoparticles on a Nd 3+ ‐doped periodically poled ferroelectric laser crystal are selectively self‐assembled by photochemical methods. By exploiting the unique features of plasmonic nanostructures to concentrate electromagnetic fields, an enhancement of Nd 3+ luminescence is demonstrated as well as a remarkable increase of the quadratic nonlinear second harmonic generation by a factor of 20, which occurs with the periodicity of the metallic arrays.
