Silicium‐Nanokristalle und Silicium‐Polymer‐Hybridmaterialien: Synthese, Oberflächenmodifikation und Anwendungen

Abstract: Aufgrund der hohen Verfügbarkeit in der Erdkruste und seiner geringen Toxizität im Vergleich zu einigen anderen Halbleitern ist Silicium der Vorreiter in der Elektroindustrie. Daher finden Silicium‐Nanokristalle (SiNKs) insbesondere aufgrund ihrer einzigartigen optoelektronischen Eigenschaften ein hohes Interesse in der Halbleiterindustrie und sie haben das Potenzial, die toxischen Quantenpunkte (Elemente der Gruppen II–VI und III–V) zu substituieren. Dennoch erhielten SiNKs wegen ihrer geringeren Photolumines… Show more

“…Most synthetic protocols produce Si terminated with either hydrides,oxides or halogens.Thiols have also been used as capping ligands for Si nanocrystals,a lthough the passivating layer is very susceptible to degradation by hydrolysis. [121][122][123] 3) Silanization is generally am ulti-step reaction:f irst of all, the surface has to be modified with an alcohol and then treated with degassed H 2 Ot od ecorate the surface with hydroxyl terminal groups.O Ht erminated nanoparticles then react with siloxane to form ac ore-shell Si@siloxane. Silyl radicals react with the terminal carboncarbon bond to induce as table SiÀCb ond.…”

“…These two functionalization processes are explained in great detail in several Reviews.

[88,124] All Si synthesis reports highlight the importance of surface modification to protect the surface,h owever only af ew articles actually report the oxidation behavior of functionalized Si nanoparticles upon contact with air.…”
