The third order nonlinear optical properties of gold nanoparticles in glasses, part I

Abstract

The optical properties of gold nanoparticles have been known for a number of years and recent advances in laser power have now allowed the non-linear optical properties to be studied. In this short review paper, the various theories that have been used to describe the optical properties of gold nanoparticles are presented. Methods of preparing gold nanoparticles in glasses are explained briefly, as well as characterization techniques. The optical properties of gold nanoparticles are reviewed, as well as the effects of particle size, shape, concentration and glass type.

Influence of laser pulse characteristics on the hot electron contribution to the third-order nonlinear optical response of gold nanoparticles

“…However, most of the studies consist essentially of experimental investigations based on either z-scan or degenerate four-wave mixing ͑DFWM͒. 10,11 In parallel, only a few theoretical works have been realized. [12][13][14] Let us mention the work of Shalaev 15 in the case of semicontinuous metal films.…”

The weird world of nanoscale gold

“…This phenomenon has been invoked as a colorimetric indicator in home pregnancy tests (14) and for testing for specific genetic sequences (15). Also, interesting non-linear optical effects are possible using gold nano-particles (16), which may find application some day in opto-electronic circuitry.…”

Enhanced nonlinear optical responses of zinc diaminopyrimidin-2-ylthio phthalocyanine conjugated to AgxAuy alloy nanoparticles

“…Research into nonlinear optical (NLO) activities of Au and Ag nanoparticles has increased in recent years as a result of their exceptional large third-order susceptibilities, and ultra-fast response time [1][2][3][4], which are needed to protect lightsensitive materials from potentially dangerous laser radiation. Research focus on optical limiting (OL) properties of metallic nanoparticle is gradually expanding and evolving from monometallic into bimetallic (Ag x Au 1-x ) [5][6][7] nanoparticles.…”
