Thermal Spin Coated PbS QD SWIR Imager for Non‐Invasive Glucose Monitoring
Advanced Science, EarlyView.Thermal spin‐coating enables controlled film formation of PbS quantum dots, leading to denser packing, reduced defect‐assisted transport, and improved carrier extraction. The resulting photodetectors exhibit suppressed dark current, enhanced responsivity, and faster response.

Why Surface Chemistry Matters for QD–QD Resonance Energy Transfer
ACS Energy Letters, 2017 Resonance energy transfer (RET) has been shown to occur in films of semiconductor quantum dots (QDs) with variation in QD composition and size. When coupled with charge carrier transfer, RET could provide a complementary strategy for light harvesting in QD based solid state photovoltaic devices.

Formation of ZnSe/Bi2Se3 QDs by surface cation exchange and high photothermal conversion
, 2015 Water-dispersed core/shell structure ZnSe/Bi2Se3 quantum dots were synthesized by ultrasonicwave-assisted cation exchange reaction. Only surface Zn ion can be replaced by Bi ion in ZnSe quantum dots, which lead to the ultrathin Bi2Se3 shell layer formed.

Advanced Science, EarlyView.A dual‐interface strategy combining a solvent‐orthogonal Poly‐TPD buffer with UV–ozone tuning of PbS‐EDT reconstructs interfacial energetics and defect chemistry in PbS CQD photodiodes. The optimized interface suppresses shunt‐ and trap‐related leakage, reduces noise, and enables high‐detectivity near‐infrared detection with imaging capability ...
