Highly‐Emissive Organic Photovoltaics Approaching Theoretical Limit Voltage and Enabling Multifunctional Energy‐Harvesting Displays

open access: yesAdvanced Materials, EarlyView.
A highly‐emissive organic photovoltaic employs donor–acceptor pairs with alternately localized frontier molecular orbitals, preserving high triplet energies and small reorganization energies to suppress non‐radiative recombination. As a result, it exhibits a high open‐circuit voltage approaching the Shockley–Queisser limit and a high ...

Quantum emitters in hexagonal boron nitride

Quantum Nanophotonic Materials, Devices, and Systems 2020, 2020
Hexagonal boron nitride (hBN) has emerged as a fascinating platform to explore quantum emitters and their applications. Beyond being a wide-bandgap material, it is also a van der Waals crystal, enabling direct exfoliation of atomically thin layers─a combination which offers unique advantages over bulk, 3D crystals.

Impedance of a Nanoantenna and a Quantum Emitter

Frontiers in Optics 2011/Laser Science XXVII, 2011
An important figure of merit of a radiowave antenna is its impedance. The purpose of this paper is to introduce a definition of the impedance for a nanoantenna and for a quantum emitter.

Superresolution Microscopy with Quantum Emitters

Nano Letters, 2013
The optical diffraction limit imposes a bound on imaging resolution in classical optics. Over the last twenty years, many theoretical schemes have been presented for overcoming the diffraction barrier in optical imaging using quantum properties of light.

Connecting quantum emitters

Science, 2018
Quantum Optics Exploiting topological properties of a system allows certain properties to be protected against the disorder and scattering caused by defects. Barik et al. demonstrate a strong light-matter interaction in a topological photonic structure (see the Perspective by Amo).

Perovskite quantum emitters

Science, 2019
Quantum Optics The development of many optical quantum technologies is dependent on the availability of solid-state single quantum emitters with near-perfect optical coherence. Light-emitting defects in diamond and quantum dots grown by molecular beam epitaxy have demonstrated transform-limited emission linewidths. However, they are limited in terms of
