Abstract Nanocavity optical trapping has enabled the isolation and precise positioning of nanoscale objects, from single molecules to quantum emitters. Yet, practically deployable single quantum sources require more than trapping, i.e., they require real-time control over position, polarization, brightness, and wavelength. Achieving such dynamic modulation remains a critical challenge, but is key to realizing ultra-secure quantum communication and adaptive quantum sensing.

Abstract A deep understanding of how the host matrix influences the afterglow properties of molecule dopants is crucial for designing advanced afterglow materials. Despite its appeal, the impact of defects on the afterglow performance in molecule-doped SiO2 matrices has remained largely unexplored. Herein, we detail the synthesis of monodisperse SiO2 microparticles by hydrothermally doping molecules, such as 4-phenylpyridine, 4,4’-bipyridine, and 1,4-bis(pyrid-4-yl)benzene.

Abstract The advancement of contemporary X-ray imaging heavily depends on discovering scintillators that possess high sensitivity, robust stability, low toxicity, and a uniform size distribution. Despite significant progress in this field, the discovery of a material that satisfies all of these criteria remains a challenge. In this study, we report the synthesis of monodisperse copper(I)-iodide cluster microcubes as a new class of X-ray scintillators.
