Novel inorganic perovskite quantum dots for photocatalysis

Nanoscale, 2017
Uniform CsPbX3 quantum dots were synthesized via an emulsion fabrication and demulsion method at room temperature. The as-prepared CsPbX3 QDs exhibit high synthetic yield and highly uniform morphology, as well as excellent photocatalytic activity toward the degradation of MO.

Colloidal-quantum-dot-in-perovskite nanowires

Infrared Physics & Technology, 2019
Abstract Colloidal quantum dots are materials of interest in infrared detection – a consequence of their near-infrared light harvesting capability, tunable bandgap, and solution-processing. Herein we develop a quantum-dot-in-perovskite-nanowire consisting of PbS quantum dots embedded inside MAPbI3 nanowires. The kinetics of perovskite nanowire growth
