Trion Formation Hampers Single Quantum Dot Performance in Silane-Coated FAPbBr3 Quantum Dots
Jessica Kline, Shaoni Kar, Benjamin F. Hammel +8
We explore silane-coated formamidinium lead bromide (FAPbBr3) quantum dots as single photon emitters and compare them to FAPbBr3 quantum dots passivated with a phosphoethylammonium…
Revealing the phonon bottleneck limit in negatively charged CdS quantum dots
Skylar J. Sherman, Bokang Hou, Matthew J. Coley-O'Rourke +4
The capture of photoexcited hot electrons in semiconductors before they lose their excess energy to cooling is a long-standing goal in photon energy conversion. Semiconductor nanoc…
Emissive Surface Traps Lead to Asymmetric Photoluminescence Line Shape in Spheroidal CsPbBr3 Quantum Dots
Jessica Kline, Shaun Gallagher, Benjamin F. Hammel +9
The morphology of quantum dots plays an important role in governing their photophysics. Here, we explore the photoluminescence of spheroidal CsPbBr3 quantum dots synthesized via th…
Ligand Equilibrium Influences Photoluminescence Blinking in CsPbBr3: A Change Point Analysis of Widefield Imaging Data
Shaun Gallagher, Jessica Kline, Farzaneh Jahanbakhshi +5
Photoluminescence intermittency remains one of the biggest challenges to realizing perovskite quantum dots (QDs) as scalable single photon emitters. We compare CsPbBr3 QDs capped w…
