Numerical research of emission properties of localized surface plasmon resonance enhanced light-emitting diodes based on Ag@SiO2 nanoparticles

Theoretical study on the lasing plasmon of a split ring for label-free detection of single molecules and single nanoparticles

“…The resonance wavelengths change with the outer radius of the SRR because the local surface plasmon resonance is closely related to the nanostructure size. [54] At the same time, both the electric field amplitudes at the two resonance modes are enhanced by hundreds of times, which indicates that the lasing light and the pumping light are both greatly enhanced. When the outer radius is smaller than 60 nm, the hybridization of different resonance modes occurs, causing fluctuations of the resonant wavelengths.…”

“…Due to the localized surface plasmon resonance and lighting rod effect, the maximum electric field is located in the gap. [54,57] In order to further understand the influence of the trapped location, we study the spectra when the nanoparticle is trapped at different locations under the condition of plasmonic lasing. The middle inset shows four different locations of the nanoparticle (r = 1.25 nm) and they are labelled as 1 to 4, respectively.…”

“…[4] As a result, the electric field is mainly located at the upper edge, rather than the lower edge of the gap. [54] The coupling between the split ring and the nanoparticle becomes weak and the shift becomes smaller.…”

Investigation of the localized surface plasmon resonance of Ag@SiO2 core-shell nanocubes and its application in high-performance blue organic light-emitting diodes

“…For example, Ag NPs can excite a strong LSPR intensity at a shorter waveband due to the strong absorption of Ag [2]. And nanocubes can excite the stronger LSPR effect than nanospheres due to their sharp edges and corners [7]. Second, the energy transfer between the LSPR field of metal NPs and the radiation field of excitons should be efficient.…”
