This study determines the optical constants of two lead‐free perovskite‐inspired materials (PIMs), Cu2AgBiI6 and Cs3Bi2I6Br3, promising for indoor light conversion. The optical constants are applied to simulate photovoltaic device optics, and thereupon, revise the theoretical limits for photocurrent generation and power conversion efficiency, providing

Thickness Dependence of Linear and Nonlinear Optical Properties of Multilayer 3R‐MoS2
Thickness as a key design parameter for optimizing the nonlinear optical response of layered transition metal dichalcogenides (TMDs) materials is established. The demonstrated correlation between thickness, linear spectra, and harmonic generation efficiency provides a powerful framework for tailoring nonlinear performance.

Ultra‐Flexible Dual‐Band Organic Photodetectors for Visible and Near‐Infrared Sensing
An ultra‐flexible dual‐band organic photodetector with a total thickness of 5.6 µm for bio‐sensing is developed. It selectively detects visible and near‐infrared light with high sensitivity by switching the voltage. Peripheral oxygen saturation (SpO2) measurement is demonstrated using the device attached to a finger under a single light source by ...

Circularly Polarized Structural Color Pigments Tunable Across the Full Visible Spectrum
By infusing black dye into spherical shells of polymerized cholesteric liquid crystal, blue, green and red omnidirectional retroreflectors of circularly polarized structural color are achieved. They can be laid out on arbitrary surfaces without any need for index matching binder to define graphical information for robots and Augmented Reality devices ...

Terahertz Chiral Recognition Based on Metasurfaces
A novel terahertz chiral sensing method based on a multilayer metallic metasurface is proposed. The left‐handed circularly polarized and right‐handed circularly polarized components in the linearly polarized illuminating light into two focal points and convert them back into linear polarization for convenient measurement.
