Iron oxide-Si nanoparticle magnetic core-shell induced by the interaction of d-orbitals of Fe2+ with reconstructed Si dimer-like defects
Elhalawany, Noha; Mantey, Kevin; Hoang, Tuan; Bahçeci, Ersin; Xu, Jiacheng; Ateş, Hakan; Gorin, Dmitry; Yamani, Zain; Nayfeh, Munir H. (American Institute of Physics Inc., 2020)Redox-type charge exchange between Si nanoparticles and aqueous metal ions m(x+) was recently used to synthesize core-shell nanocomposites in which their functionalities have been integrated. The process requires the ... -
Wet non-thermal integration of nano binary silicon-gold system with strong plasmonic and luminescent characteristics
Enders, Brian; Koçyiğit, Adem; Bahçeci, Ersin; Elhalawany, Noha; Nayfeh, Ammar; Alshammari, Owrad; Alsalhi, Mohamad; Nayfeh, Munir (Amer Inst Physics, 2019)We report on a wet none thermal integration of the binary silicon-gold nano system. Instead of thermally based gas-solid procedures, we use charge exchange/injection-based procedures in a chemical wet environment. SEM and ... -
Wideband luminescence from bandgap-matched Mg-based Si core-shell geometry nanocomposite
Kocyiğit, Adem; Elhalawany, Noha; Bahçeci, Ersin; Enders, Brian; Puthalath, Krithik; Abuhassan, Laila; Yamani, Zain; Nayfeh, Munir (American Institute of Physics Inc., 2018)We use wet treatment to integrate red-luminescent Si nanoparticles with Mg-based wide-bandgap insulators Mg(OH) and MgO (5.7 and 7.3 eV respectively). In the process, Mg2+ is reduced on Si nanoparticle clusters, while ...
