We present a cost effective non-lithographic approach to fabricate metal nano-particles on an In0.2Ga0.8As quantum well (QW) structure. A highly ordered nano-hole array honeycomb structure is created using anodic oxidation of aluminium (Al). This structure provides a template for deposition of metal from which further processing yields metal nano-particles on a QW structure. We will compare how different...
Two-photon-excited fluorescence (TPEF) enhancement of a semiconductor quantum dot (SQD) adsorbed on a Au nanoparticle (NP) was investigated theoretically. Surface plasmon resonance (SPR) enhancement of the exciting light and radiative rate of the SQD, and nonradiative energy transfer (NRET) from SQD to Au NP were taken into account. Compared to the unitary enhancement factor obtained from considering...
Surface plasmon (SP) excitation is important for integrated plasmonic circuits. This study covers experimental and numerical studies of far-field excitation of propagating SPs using engineered local plasmon resonances.
Surface plasmon resonance (SPR) of metal-dielectric composite films formed by noble metal nanoparticles embedded in a dielectric is very sensitive to the changes in the refractive index of the dielectric induced by physical absorption or chemical reactions and is therefore exploited for gas sensing applications. In this study, Au-WO3-x nanocomposite thin films were fabricated by pulsed laser deposition...
