摘要：
This paper summarizes a detailed study of plasmon-enhanced/quenched fluorescence of gold nanoparticles (NPs) and rhodamine 6G (R6G) dye complexes. Spectral fluorescent properties of the complexes with/without SiO2 shell have been investigated. FDTD modeling of optical parameters has been carried out. Mesoporous silica nanoparticles (MSNs) have been added to the system in the case of Au@SiO2 NPs. The influence of SiO2 shells and MSNs on the photophysical properties of the complexes studied has been demonstrated.
