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…
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…
Increased Brightness and Reduced Efficiency Droop in Perovskite Quantum Dot Light-Emitting Diodes using Carbazole-Based Phosphonic Acid Interface Modifiers
Gillian Shen, Yadong Zhang, Julisa Juarez +8
We demonstrate the use of [2-(-carbazol-9-yl)ethyl]phosphonic acid (2PACz) and [2-(3,6-di--butyl--carbazol-9-yl)ethyl]phosphonic acid (t-Bu…
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…
