Nonlinear optical properties of Cu nanoclusters by ion implantation in silicate glass

Optical Nonlinearities of Colloidal Metal Quantum Dot - Glass Composites for Nanophotonics

“…The nonlinear optical properties of the copper colloids were first measured using the Z-scan technique and () 3 χ values obtained were found to be of the order of 10 -11 −10 -12 esu. Recently reported works includes synthesis of metal nanocluster composite glass by Cu ions implanted into silica with dose of 1 × 10 17 ions/cm [61,62]. Third-order nonlinear optical properties of the nanoclusters were measured at 1064 nm and 532 nm excitations using Z-scan technique.…”

The Preparation and Characterization of Copper-Containing Thin Films Prepared by the Sol-Gel Method on Various Glasses

“…Copper can be present in glass in three stable oxidation states, each of which gives glass unique properties resulting in the different utilization of the glasses. Cu(0) nanoparticles introduce a ruby-red coloration of glass due to absorption with the maximum between 550 and 570 nm, a consequence of surface plasmon resonance, which gives such glass nonlinear optical properties [1][2][3][4]. Glasses containing copper in oxidation states, Cu(I) or Cu(II), create planar optical waveguides, which can be utilized in both passive (divalent copper) and active (monovalent copper) devices [5,6].…”

Poly(N-isopropylacrylamide-co-methacrylic acid) microgel stabilized copper nanoparticles for catalytic reduction of nitrobenzene

“…Therefore, it is a need of time that we should have cheap but efficient catalysts. Copper (Cu) nanoparticles are cheap and highly conducting, therefore, they are enormously being used in nano electric, photonic [13], catalytic [14] and * E-mail: zhfarooqi@gmail.com biological fields [15,16]. Wu et al [17] have synthesized Cu nanoparticles using cetyltrimethylammonium bromide surfactant as stabilizing agent.…”
