Investigation of carrier dynamics of QDs using kinetic model and ultrafast spectroscopy
Optical Materials: X, 2022 The study of carrier dynamics of QDs is extremely important for developing efficient light-harvesting systems. Here, we investigate size-dependent hole transfer from CdSe QDs to 4-aminothiophenol (4-ATPh) ligand using ultrafast spectroscopy.

Quantum dots transparent display (QDs-TPD) using a liquid QDs layer and N2 barrier discharge
, 2017 Quantum dots transparent display (QDs-TPD) was realized using a liquid QDs layer and N2 barrier discharge panel. In the N2 discharge, the 2nd+ lines of N2 in the range of 300 - 400 nm (C3Πu – B3Πg), and the 1st- lines of N2+ at 391.4 and 427.8 nm (B2Σu+ -

Suppressed Blinking Dynamics of Single QDs on ITO
, 2016 The exciton quenching dynamics of single CdSe/CdS3MLZnCdS2MLZnS2ML core/multishell QDs adsorbed on glass, In2O3, and ITO have been compared. Single QDs on In2O3 show shorter fluorescence lifetimes and higher blinking frequencies than those on glass ...

Facet‐Specific PbS Quantum Dot Passivation Using Halide Perovskites for SWIR Photodetectors
Advanced Materials Interfaces, EarlyView.PbS quantum dots (QDs) are emerging as powerful short‐wave infrared photodetectors, yet the passivation mechanism of large QDs by perovskites ‐ critical for their stability ‐ remains unexplained. Here, we unveil the ligand structure of CH3NH3PbI3 (MAPI)‐passivated 4‐nm PbS QDs using FTIR, XPS, SEM, NMR, and DFT.
