“…And quantum confinement effect is attributed to the small size effect, which alters the electronic structures of nanocrystals from those of the bulk materials. Generally, there are three major mechanisms contributing to the optical nonlinearity in small metal particles: interband transition between the d band and the conduction band, intraband transition in the quantum confined conduction band, and hot-electron contribution [35,36]. The first one transitions from the upper levels of the filled d band to the levels above the Fermi level in the conduction band and the second one corresponds to transitions within the conduction band [37].…”

“…Some studies have reported the preparation and NLO properties of inorganic nanocomposite materials with noble metals [66]. Herein, Sun et al [67] reviewed on recent theoretical progress in understanding the nonlinear optical response of noble metal nanocomposite materials with an enhanced thirdorder nonlinear susceptibility application on optical switchers and optical limiters. The enhanced third-order nonlinear susceptibility results from the surface plasmon resonance of noble metal nanoparticles, which strongly depends on irradiation light wavelength, concentration, and surrounding medium of noble metal particles.…”

Nonlinear optical (NLO) materials have gained much attention during the last two decades owing to their potentiality in the field of optical data storage, optical information processing, optical switching, and telecommunication. NLO responsive macroscopic devices possess extensive applications in our day to day life. Such devices are considered as assemblies of several macroscopic components designed to achieve specific functions. The extension of this concept to the molecular level forms the basis of molecular devices. In this context, the design of NLO switches, that is, molecules characterized by their ability to alternate between two or more chemical forms displaying contrasts in one of their NLO properties, has motivated many experimental and theoretical works. Thus, this chapter focuses on the rational design of molecular NLO switches based on stimuli and materials with extensive examples reported in the literature. The factors affecting the efficiency of optical switches are discussed. The device fabrication of optical switches and their efficiency based on the optical switch, internal architecture, and substrate materials are described. In the end, applications of switches and future prospectus of designing new molecules with references are suitably discussed.

“…24,25 Actually, Neeves et al theoretically predicted the enhancement of χ (3) (ω) on the basis of the concept of "excitation enhancement" in the core−shell type hybridized NPs. 26 In fact, some hybridized systems have been reported so far, 27,28 in which noble metal NPs were loaded and dispersed in π-conjugated polymer matrix thin films. However, the correlations between enhancement of χ (3) (ω) and hybridized nanostructure still remain equivocal and unclear even in abovedescribed such kinds of hybridized systems.…”

Third-Order Nonlinear Optical Properties of Layered Type Hybridized Thin Films Consisting of Oriented Polydiacetylene Nanofibers and Silver Nanoparticles

Layered type hybridized thin films, which were composed of oriented polydiacetylene (PDA) nanofibers (NFs) and silver (Ag) nanoparticles (NPs), have been fabricated successfully by means of the alternative processes of the layer-by-layer (LbL) method and the convective assembly method. The wavelength dispersion of third-order nonlinear optical (NLO) susceptibility, χ (3) (ω), and the corresponding figure of merit (FOM) have been evaluated correctly by the combined analysis with femtosecond pump−probe spectroscopy and spectroscopic ellipsometry. It has become apparent that both χ (3) (ω) and FOM were enhanced evidently in the layered type hybridized thin films under the optimized condition of a suitably adsorbed amount of Ag NPs, compared with random thin films of PDA NFs and/or oriented thin films of PDA NFs, because of the localized surface plasmon resonance (LSPR) effect from Ag NPs as well as the orientation effect of PDA NFs. This would provide a new design guide for organic NLO hybrid nanomaterials toward photonic device applications.
