Tuning Charge‐Separated State Lifetimes in Perovskite Nanocrystal‐Perylenediimide Hybrids

open access: yesAdvanced Optical Materials, EarlyView.
Functional perylenediimides with varied spacer lengths surface engineer CsPbBr₃ perovskite nanocrystals, yielding hybrid materials with new properties. Time‐resolved techniques reveal photoinduced charge separation from perovskite nanocrystals to perylenediimides, with microsecond‐lived charge carriers. Spacer length modulates charge carrier lifetimes,

Coherent Control of Thermal Radiation with Nanophotonics

open access: yesAdvanced Photonics Research, EarlyView.
This review explores the innovative control of thermal radiation coherence using nanophotonic structures. The fundamentals of thermal radiation, coherence control strategies (temporal, spatial, and polarization), and their applications in infrared sensing, radiative cooling, thermal camouflage, and imaging, are discussed.

Pressure‐Assisted Ceramic Processing of Metal Halide Perovskites

open access: yesAdvanced Photonics Research, EarlyView.
This review critically assesses low‐temperature, pressure‐assisted ceramic processing as a pivotal technique to fabricate dense, polycrystalline wafers with precisely controlled macroscopic dimensions as well as microstructural properties. The aim is to bridge understanding between expert ceramists and halide perovskite specialists, highlighting the ...

Experimental Test of the Three‐Setting Clauser–Horne–Shimony–Holt Inequality with Nonmaximally Orbital Angular Momentum Entangled States

open access: yesAdvanced Photonics Research, EarlyView.
Herein, the maximum violation of the three‐setting Clauser–Horne–Shimony–Holt (CHSH) inequality using nonmaximally entangled photons with orbital angular momentum is demonstrated. By mapping the optimization problem to maximizing a triangle's perimeter inscribed in an ellipse, the experiment validates the geometric approach and highlights the ...
