Sychov4 EFFECT OF Ag AND Cl IONS ADDITION UPON THE FORMATION OF CuCl NANOPARTICLES IN FLUOROPHOSPHATE GLASSES St. Petersburg State Institute of Technology (Technical University), Moskovsky Pr., 26, St Petersburg, 190013, Russia e-mail: ph_abdelghany@yahoo.com The addition of Ag ions into CuCl-containing fluorophosphate glasses is found to result in a change of crystallization mechanism and growth of CuCl nanocrystals via a heterogeneous nucleation. <...> Depending on Cl ions addition either AgCl clusters or Agn , M.I. Abdelghany, Е. <...> Сычев ВЛИЯНИЕ ВВЕДЕНИЯ ИОНОВ СЕРЕБРА И ХЛОРА НА ФОРМИРОВАНИЕ НАНОЧАСТИЦ CuCl ВО ФТОРФОСФАТНОМ СТЕКЛЕ Санкт-Петербургский государственный технологический институт (технический университет), Московский пр., 26, Санкт-Петербург, 190013, Россия e-mail: ph_abdelghany@yahoo.com . nanoclusters act as nucleating agents in the excess or reduced amount of chlorine correspondingly. <...> The appearance of surface plasmon resonance bands in the spectra of the studied glasses suggests the growth of Cu and Ag nanoparticles. <...> Keywords: nanocrystals, CuCl, excitons, fluorophosphate glass DOI 10.15217/issn1998984-9.2016.34.40 For the recent years, the formation of semiconductor Introduction nanocrystalline phases in a glass matrix as well as the control of their properties are considered as important problems in the technology of nanostructured materials preparation. <...> The effect of quantum confinement on the optical properties of semiconductor materials and glasses containing NPs was studied in [2, 3]. <...> CuCl NCs demonstrated strong exciton absorption in the near-UV spectral region that is useful for their application in optical filters with sharp absorption edge at the UV region boundary providing the cutoff of UV radiation and transparency in visible – near IR spectral ranges [4]. <...> Glasses with CuCl NCs are characterized by high nonlinear optical response and photochromism [5, 6]. <...> FP glass containing CuCl NCs do not possess any photochromic properties, in contrast to borosilicate glass [7, 8]. <...> Nanoscale particles of transition metals like Ag, Au, and Cu embedded in glass as the dielectric matrix are of great interest because of their potential applications in the field of photonics owing to their unique optical characteristics origi1 2 3 <...>
