Nonlinear optical properties of silver nanoparticles prepared in Ag doped borate glasses

Preparation and nonlinear optical properties of LiCaBO3–Ag2O and LiCaBO3–Gd2O3–Ag2O borate glasses with Ag nanoparticles

“…This makes nanocomposites on basis of borate glasses to be potentially prospective for photonics . Nevertheless, in mentioned works there were revealed both similarities and differences of Ag NPs formation in Li 2 B 4 O 7 and CaB 4 O 7 glass matrices. The similarity is that the formed Ag NPs are concentrated on surface of the glass samples at annealing of Li 2 B 4 O 7 :Gd,Ag and CaB 4 O 7 :Gd,Ag glasses in vacuum.…”

“…Transformation of Ag + ions to neutral Ag 0 state by thermal treatment of Ag saturated glass in reducing atmospheres is the main method for Ag nanoparticles (Ag NPs) formation in matrices . In our previous publications , we had informed about successful application of borate glasses of B 2 O 3 –Li 2 O and B 2 O 3 –CaO systems for formation of nanocomposites with Ag NPs. The borate compounds are defined by high values of nonlinear susceptibilities of boroxol complexes and it is an important advantage for application of borate compounds for Ag NPs formation .…”

“…The borate compounds are defined by high values of nonlinear susceptibilities of boroxol complexes and it is an important advantage for application of borate compounds for Ag NPs formation . The investigations of Li 2 B 4 O 7 :(Ag NPs) , Li 2 B 4 O 7 :Gd,(Ag NPs) , CaB 4 O 7 :(Ag NPs), and CaB 4 O 7 :Gd,(Ag NPs) nanocomposites have shown that the plasmon resonance on Ag NPs has significant influence on their nonlinear properties. This makes nanocomposites on basis of borate glasses to be potentially prospective for photonics .…”

Nonlinear optical parameters of borate glasses with Ag nanoparticles formed using reducing Gd3+ ions

“…Especial interest is connected with nanocomposites consisting of dielectric materials, or matrices in which metal NPs are formed. Today a significant portion of attention of researchers is paid to formation of Ag NPs in different glass matrices [6][7][8][9][10][11][12][13][14][15]. Indeed, the plasmon resonance bands for this metal, which are caused by the Ag NPs, are observed in a very convenient visible spectral range (400-500 nm or so).…”

“…In our previous works [11,[13][14][15], the Ag NPs in a number of borate glasses (BGs) such as Li 2 B 4 O 7 :Ag and CaB 4 O 7 :Ag have been formed through annealing the latter in vacuum or in reducing hydrogen atmosphere. Note that it has been virtually impossible to form Ag NPs in the Li 2 B 4 O 7 :Ag and CaB 4 O 7 :Ag glasses when the glasses are annealed in the air.…”
