Diameter Dependence of Light Absorption in GaAs Nanowires Evidenced by Photoluminescence Spectroscopy

Advanced Optical Materials, EarlyView.
Photoluminescence spectroscopy is introduced as a qualitative method to probe light absorption in highly phase‐pure GaAs nanowire arrays and single nanowires, for which direct absorption measurements are challenging. Using defect‐line saturation and the exciton‐to‐plasma transition as indicators for the density of photogenerated charge carriers, a ...

Probing Ultrafast Coherent Bandgap Modulation in Monolayer WSe2 by Nonlinear Optics

Advanced Optical Materials, EarlyView.
This work sheds light on how resonant nonlinear optics blursthe line between perturbative and non‐perturbative nonlinear optics. Measured deviationsfrom the quadratic second‐harmonic scaling near the excitonic resonance arisefrom optical Stark and Bloch‐Siegert shifts. The experimental results arefurther underpinned by analytical and numerical analysis

Spectroscopic Ellipsometry Characterization and Radiative Limit Modeling of Bismuth‐Based Perovskite‐Inspired Absorbers for Indoor Photovoltaics

Advanced Optical Materials, EarlyView.
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
