Electrical control of single-photon emission in highly-charged individual colloidal quantum dots
Sergii Morozov, Evangelina L. Pensa, Ali Hossain Khan +6
Electron transfer to an individual quantum dot promotes the formation of charged excitons with enhanced recombination pathways and reduced lifetimes. Excitons with only one or two…
Objective-free excitation of quantum emitters with a laser-written micro parabolic mirror
Sergii Morozov, Stefano Vezzoli, Ali Hossain Khan +2
The efficient excitation of quantum sources such as quantum dots or single molecules requires high NA optics which is often a challenge in cryogenics, or in ultrafast optics. Here…
Dye-Sensitized Ternary Copper Chalcogenide Nanocrystals: Optoelectronic Properties, Air Stability and Photosensitivity
Sonam Maiti, Santanu Maiti, Ali Hossain Khan +5
We report on the effect of ligand exchange of copper sulphide selenide as well as copper selenide nanocrystals with the organic pi-system Cobalt beta-tetraaminophthalocyanine and a…
Colloidal Synthesis of Strongly Fluorescent CsPbBr3 Nanowires with Width Tunable down to the Quantum Confinement Regime
Muhammad Imran, Francesco Di Stasio, Zhiya Dang +6
We report the colloidal synthesis of strongly fluorescent CsPbBr3 perovskite nanowires (NWs) with rectangular section and with tuneable width, from 20 nm (exhibiting no quantum con…
