Transmission and reflection coefficients of periodic metallic nanospheres structures in the visible

Summary form only given. We have shown that the coherent collective effects in close-packed monolayers of silver nanoparticles result in a long-wave (in relation to isolated particles) shift of the plasmon resonance frequency and plasmon resonance peak amplification and broadening. In the case of a stack of such monolayers with appropriate thickness of solid intermediate films there is a stop band in the visible, corresponding to the formation of the photonic band gap due to one-dimensional ordering of the nanoparticle system. Formation of the photonic stop band is accompanied by an additional shift of the extinction resonance associated with plasmon absorption.
