Plasmon-enhanced ZnO whispering-gallery mode lasing

Hybrid quadrupole plasmon induced spectrally pure ultraviolet emission from a single AgNPs@ZnO:Ga microwire based heterojunction diode

“…Thus, the PL emission enhancement of a single ZnO:Ga MW with Ag nanoparticle decoration cannot be attributed to resonant coupling between ZnO:Ga excitons and AgNPs plasmons at the interface. 21,22,55 When the output radiation from the heterojunction LED is absorbed by the deposited Ag nanoparticles, hybrid quadrupole plasmons can be excited. Aer excitation, nonradiative decay can occur through intraband excitations within the conduction band or through interband excitations, leading to transitions between the conduction band and other bands.…”

“…The incorporation of metal nanostructures, predominantly in their elemental forms, can be employed to signicantly modulate the optical and optoelectronic performances of semiconductors. [17][18][19][20][21] By incorporating noble metal nanostructures, such as Ag nanoparticles, the localized surface plasmon resonance effect has been considered to be an efficient strategy to enhance the luminous efficiency of light-emitting materials and devices, with ZnO micro/nanostructures serving as active layers. [22][23][24] Due to the small sizes of the plasmonic nanostructures, the optical response of the spherical nanostructures embedded in the dielectric materials exhibits dipole surface plasmon resonance modes, which result in strong attenuation of incident light.…”

Resonant energy transfer and light scattering enhancement of plasmonic random lasers embedded with silver nanoplates

“…Owing to its superior LSPR in the near UV regime in comparison to the gold nanoparticles, a number of studies have focused on the enhancement of RL by means of different morphology AgNPs. 33 Through mechanical stress, a tunable PRL has been reported from the waveguiding plasmonic gain channel on top of a exible silicon rubber slab comprising of silver nanowires. 34 Based on solution preparation strategies using chemical reduction, 35 the tremendous tailoring ability of the lateral size of AgNPs relative to their thickness can be achieved to shi the wavelength of LSPR.…”

Enhanced Second‐Harmonic Generation in a Single Microwire Based on Localized Surface Plasmon

“…For the interaction between LSP and semiconductors, two processes, including surface plasmon coupling‐induced field enhancement and hot electron transfer, will dominate . Due to SHG is a parametric process, hence, hot electron transfer will not disturb the SHG .…”
