Nonlinear optical response of Au and Ag nanoparticles doped polyvinylpyrrolidone thin films

Poly(vinylpyrrolidone) – A Versatile Polymer for Biomedical and Beyond Medical Applications

“…Metal nanoparticles show diverse applications in a variety of fields, such as flexible photonics and electronics, surfaceenhanced Raman scattering, medical imaging, diagnosis and therapy, labelling of biological molecules, optical biosensors [105] , but also in commercial paintings and local heat sources for targeted cancer tumoral cell destruction [118] . Gold and silver nanoparticles-doped PVP composites where prepared by He et al, for different applications in optical devices [118] .…”

“…Gold and silver nanoparticles-doped PVP composites where prepared by He et al, for different applications in optical devices [118] . The composite thin films exhibit strong nonlinear absorption and nonlinear refraction under picoseconds laser pulse excitation.…”

Characterization of thermal diffusivity and optical properties of Ag nanoparticles

“…In addition, the nonlinear optical properties of metal nanofluids and metal nanocomposites, such as nonlinear refractive index and nonlinear absorption have also been widely investigated and reported elsewhere [9][10][11][12][13]. The nonlinear optical properties of metal Au and Ag colloidal solutions prepared by the chemical reaction method were reported by Jia et al (2008).…”

Saturable absorption and two-photon absorption of 1,2,5-thiadiazolo[3,4-g]quinoxaline based derivatives with near-infrared fluorescence

“…There are two distinct nonlinear absorption processes: reverse saturable absorption and the saturable absorption (SA) [2][3][4]. Two-photon absorption (TPA) is one of the most important reverse saturable absorption behaviors, which has attracted growing interest over recent years due to the many applications in multiphoton microscopy, optical limiting, frequency-upconversion lasing, pulse stabilization and reshaping [1].…”
