Toward quantum adaptive imaging: wavefront sensing of position-correlated biphotons

Light Publishing Center, Changchun Institute of Optics, Fine Mechanics And Physics, CAS
Peer-Reviewed Publication

Entangled photon pairs enable several quantum imaging techniques. However, a spatial phase aberration can degrade the image quality. To develop a more efficient biphoton phase measurement method, researchers in China proposed position-correlated biphoton Shack–Hartmann wavefront sensing. By using a microlens array, the phase pattern added to biphotons with a strong position correlation can be reconstructed after a single-shot joint probability measurement. This method holds great potential in future real-time quantum adaptive imaging researches.

Recyclable luminescent solar concentrator from lead-free perovskite derivative

Light Publishing Center, Changchun Institute of Optics, Fine Mechanics And Physics, CAS
Peer-Reviewed Publication

By using a lead-free perovskite derivative ETP₂SbCl₅ (ETP = (C₆H₅)₃PC₂H₅), Li's group fabricate a series of recyclable LSCs, achieving the highest power conversion and optical efficiencies of ~5.56% and ~32.5%, respectively. The damaged LSCs could be mass recycled to phosphor by ethanol or mild heating treatments, which still maintains nearly initial fluorescent performance. This work presents a paradigm for the sustainable use of fluorescent materials and offers a reliable path toward low-carbon globalization.

Ultralong organic afterglow from small molecular host-guest materials: State of the art

Light Publishing Center, Changchun Institute of Optics, Fine Mechanics And Physics, CAS
Peer-Reviewed Publication

Ultralong organic afterglow materials are being actively explored as attractive candidates for a wide range of applications such as data storage, security inks, emergency lighting, etc. In this review, the research team have summarized small-molecule ultralong organic afterglow materials based on different emission mechanisms involving ultralong room-temperature phosphorescence (URTP), ultralong thermally activated delayed fluorescence (UTADF) and organic long persistent luminescence (OLPL). In addition, challenges and future perspectives are discussed to emphasize the future directions.
