When blinking helps: enhanced single-photon purity in the off states of perovskite quantum dots
Adam Olejniczak, Jehyeok Ryu, Francesco Di Stasio +2
Photoluminescence blinking typically degrades the single-photon purity of quantum dot emission. Here, we show that individual CsPbBr perovskite quantum dots (PQDs) can exhibit…
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…
High Open Circuit voltage solar cells based on bright mixed halide CsPbBrI2 perovskite nanocrystals synthesized under ambient air conditions
Sotirios Christodoulou, Francesco Di Stasio, Santanu Pradhan +2
Lead halide perovskite nanocrystals (NCs) are currently emerging as one of the most interesting solution processed semiconductors since they possess high photoluminescence quantum…
Multirate 5G Downlink Performance Comparison for f-OFDM and w-OFDM Schemes with Different Numerologies
Francesco Di Stasio, Marina Mondin, Fred Daneshgaran
One of the main open problems for next generation wireless networks, is to find the new OFDM-based waveform to be used in 5G. The new modulation scheme must primarily be able to ac…
