Designed nanoparticle-mesoporous multilayer nanocomposites as tunable plasmonic-photonic architectures for electromagnetic field enhancement

In this work we present the designed production of a highly tunable nanocomposite able to confine and enhance the electromagnetic field through the combined effects of photonic and plasmonic responses. Silver nanoparticles (NPs) were embedded within a Mesoporous Photonic Crystal (MPC) composed of a...

description In this work we present the designed production of a highly tunable nanocomposite able to confine and enhance the electromagnetic field through the combined effects of photonic and plasmonic responses. Silver nanoparticles (NPs) were embedded within a Mesoporous Photonic Crystal (MPC) composed of a mesoporous multilayer presenting a TiO2-SiO2 unit cell. This nanosystem was synthesized by a combination of reproducible sol-gel thin film techniques with the selective production of NPs within the titania layers. The design of the MPC architecture was tuned so that each photonic band gap edge would match the plasmonic absorption peak of the Ag NP, in order to combine their confined plasmonic enhancement with that of the band gap edges due to the multilayer structure.
