Cheng-Wei LuJing FuJi-Long Hao Article Open Access 27 Jul 2023 Controlling the electro-optic response of a semiconducting perovskite coupled to a phonon-resonant cavity We investigate the ultrafast optoelectronic response of semiconducting perovskite in an optically transparent terahertz cavity. Despite apparent polariton formation and strong electron-phonon coupling, the cavity-coupled material properties remain unchanged. Lucia Di VirgilioJaco J.

Bozhang DongMario DumontJohn E. Bowers Article Open Access 25 Jul 2023 Intervalence charge transfer of Cr3+-Cr3+ aggregation for NIR-II luminescence Intervalence charge transfer (IVCT) for NIR-II luminescence was first reported in heavy Cr3+ doped LaMgGa11O19:Cr3+. The luminescence exhibits anti-thermal quenching behavior (432% @ 290 K), capable of NIR-II spectroscopy applications.
