“…To examine the influence of metal nanoparticles on the photoluminescence of semiconductors, colloidal mixtures of CdS and Au nanoparticles were prepared with different CdS/Au fractions. [58] The photoluminescence emission spectra of the mixed CdS/ Au nanoparticles were measured under excitation of 400 nm at room temperature ( Fig. 11(a)).…”

Semiconductor nanoparticles have recently attracted a significant amount of attention from the materials science community. Nanoparticles with diameters in the range of 1 nm to 20 nm exhibit unique physical properties that give rise to many potential applications. Two fundamental factors are crucial as regards the novel properties of semiconductor nanoparticles. The first is the large surface-to-volume ratio. In this regard, the surface states are likely to trap electrons and/or holes, and induce a nonradiative recombination of these charge carriers, leading to a reduction in the luminescent and photovoltaic efficiency. The second approach takes advantage of the surface-plasmon resonance from metal nanostructures to semiconductors. The interactions between the semiconductor nanoparticles and the surface plasmons generate enhanced emission by electromagnetic-field amplification, and also causes the suppression of the emission by the energy transfer between the semiconductor and the metal nanoparticles. Therefore, surface passivation and surface plasmon in semiconductor nanoparticles with controlled nanostructures are important when attempting to improve both the luminescent and photovoltaic efficiency.

Abstract. The influence of the surface plasmon of gold nanoparticles on the optical properties of the fluorescent nanoparticles in aqueous solution have been investigated. The fluorescence of nanoparticles can be enhanced or quenched in the presence of gold nanoparticles depending on the domination of energy transfer mechanisms: radiating surface plasmon coupling emission or Förster energy transfer from fluorescent particles to gold particles, which exciting absorbing plasmon. The fluorescence enhancement or quenching is attributed to the increase or decrease of radiative recombination rates, respectively. The parameters of the energy transfer between fluorescent nanoparticles (dye molecules encapsulated in silica nanoparticles) and nano golds have been estimated. The results show that the interactions between nanoparticles depend on the size of both fluorophores (as donors) and gold nanoparticles (as acceptors).

“…Obviously, the FRET follow the opposite behavior of the PL lifetime due to it mainly depend on it. [42] In addition to the cross-section values, the effectiveness of a laser oscillator or amplifier is strongly affected by the amount of resonant absorption at the extraction wavelength. In this case it is essential to estimate some spectroscopic parameters (β min , I sat and I min ) that being used for evaluating the lasing properties of the material.…”
