Optical nonlinearities of Au nanocluster composite fabricated by 250keV ion implantation

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

“…Increased attention has focused on the third-order nonlinear susceptibility and the photorefractive effect of noble-metal clusters embedded in dielectric matrices [1][2][3]. Third-order nonlinearities of metal/dielectric composite materials are influenced not only by the type and size of the embedded metal clusters, but also by the dielectric constant, thermal conductivity and heat capacity of the dielectric matrices [1][2][3][4][5][6].…”

The most conspicuous manifestation of confinement in optical properties of metal nanocluster composite glasses (MNCGs) is the appearance of the surface plasmon resonance (SPR) that strongly enhances their linear and nonlinear responses around SPR wavelength [7][8][9].…”

Enhanced photo-response of thin-film structures with nanocrystals

“…Unfortunately, not only bulk, but boundary (surface) states of nanocrystals affect strongly their physical properties as their size reduces [14]. The properties of thin layers and nanocrystals as prepared and post-growth processed by different methods can be affected by the presence of impurities, crystal defects and aggregation of impurities and intrinsic defects to the colloids in the bulk and surface regions [13,[15][16][17][18][19][20] related to the used preparation technique.…”

“…Ion implantation [17], thermal treatments [18] and ionising radiation bombardment (combined with special annealing [15,16,19,20]) are established tools for metal nanoparticles formation in solids. Understanding the structural evolution during the preparation of nanocomposites can be of great help in understanding how to control the characteristics of the final products.…”
