When Blinking Helps: Suppressed Biexciton Emission in Lead Halide Perovskite Quantum Dots
Adam Olejniczak, Jehyeok Ryu, Francesco Di Stasio +2
Blinking and multiphoton emission in metal halide perovskite quantum dots (PQDs) limit their use as single-photon quantum emitters. Conventional models distinguish between trion-re…

Improving the Stability of Colloidal CsPbBr3 Nanocrystals with an Alkylphosphonium Bromide as Surface Ligand Pair
Meenakshi Pegu, Hossein Roshan, Clara Otero-Martinez +9
In this study, we synthesised a phosphonium-based ligand, trimethyl(tetradecyl)phosphonium bromide (TTP-Br), and employed it in the post-synthesis surface treatment of Cs-oleate-ca…

Enhanced vibrational optical activity by near-zero index chiral effective media
Ashis Paul, Matteo Venturi, Raju Adhikary +8
The enhancement of the inherently weak optical activity of solvated molecules by superchiral fields, crucial for detecting their chirality, is a research frontier of photonics and…
