Bright room temperature single photon source at telecom range in cubic silicon carbide
It is found that bright single-photon emitters in cubic silicon carbide (3C-SiC) emitting in the telecom range are photostable and bright at room temperature with a count rate of ~ MHz.
Room temperature solid-state quantum emitters in the telecom range
An optically stable, room temperature single-photon emitter operating in telecom wavelength range is discovered in GaN, attributed to localized defects in a gallium nitride (GaN) crystal.
Efficient Generation of an Array of Single Silicon-Vacancy Defects in Silicon Carbide

Efficient Inverted Perovskite Solar Cells by Employing N-Type (D-A1 -D-A2 ) Polymers as Electron Transporting Layer.
This study reveals that the n-type polymers can be promising candidates as ETLs to approach solution-processed highly-efficient inverted PSCs and shows a neglected hysteresis.
Scalable Fabrication of Single Silicon Vacancy Defect Arrays in Silicon Carbide Using Focused Ion Beam
In this work, we present a method for scalable, targeted, and maskless fabrication of single silicon vacancy (VSi) defect arrays in silicon carbide using focused ion beam. First, we studied the…
Anti-Stokes excitation of solid-state quantum emitters for nanoscale thermometry
This work reports that the anti-Stokes process is sufficiently efficient to excite even a single quantum system—namely, the germanium-vacancy center in diamond, and leverages the temperature-dependent, phonon-assisted mechanism to realize an all-optical nanoscale thermometry scheme that outperforms any homologous optical method used to date.

This investigation designed and synthesized two naphthalenediimide (NDI) derivatives and found that introduction of 2-(benzo[d]thiazol-2-yl) acetonitrile groups at NDI core position gave lowest unoccupied molecular orbital and displayed strong electron affinities, suggesting that NDI-BTH1 might be a promising electron transporting material.
