Sonication-assisted ion-intercalation exfoliation of MoS2 quantum dots

Sonication-assisted ion-intercalation exfoliation of MoS2 quantum dots

Synthesis of MoS 2 quantum dots (QDs) by a sonication-assisted ion-intercalation process where sodium hydroxide (NaOH) is used as sodium (Na + ) and hydroxyl (OH − ) ions source for the intercalation purpose is reported. The exfoliation method results in well-exfoliated mono- to few-layered QDs as i...

Zusammenfassung:Synthesis of MoS 2 quantum dots (QDs) by a sonication-assisted ion-intercalation process where sodium hydroxide (NaOH) is used as sodium (Na + ) and hydroxyl (OH − ) ions source for the intercalation purpose is reported. The exfoliation method results in well-exfoliated mono- to few-layered QDs as illustrated by the atomic force microscopy (AFM) measurements, showing a thickness of
