Etched graphene quantum dots on hexagonal boron nitride [PDF]
, 2013 We report on the fabrication and characterization of etched graphene quantum dots (QDs) on hexagonal boron nitride (hBN) and SiO2 with different island diameters. We perform a statistical analysis of Coulomb peak spacings over a wide energy range.

Electrospun Nanofibers prepared with CdTe QDs, CdTeSe QDs and CdTe/CdS Core-shell QDs
Celal Bayar Üniversitesi Fen Bilimleri Dergisi, 2018 In this study, a novel method is used to prepare water-soluble CdTe, CdTeSe quantum dots (QDS) and CdTe/CdS core-shell QDs by using Te, Se, NaBH4, and CdCl2 as precursors. Electrospinning method is used to obtain polyvinyl alcohol (PVA)/QDs composite nanofibers.

Synthesis of Colloidal Silicon Quantum Dot from Rice Husk Ash
Journal of Chemistry, 2021 This article describes the synthesis procedure of colloidal silicon quantum dot (Si QDs) from rice husk ash. The silicon quantum dots were capped with 1-octadecene by thermal hydrosilylation under argon gas to obtain octadecyl-Si QDs (ODE-Si QDs).
