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

Advanced Optical Materials, EarlyView.This work dissects the ultrafast response of polydisperse plasmonic nanorods using two‐dimensional electronic spectroscopy, uniquely combining temporal and spectral resolution. Our ultrabroadband pulses cover both transverse and longitudinal nanorods’ resonances, revealing sub‐200‐fs dynamics and distinct broadening mechanisms.

Advanced Optical Materials, EarlyView.Selective growth protocols are established to obtain high‐quality bulk single crystals of the 2H and 3R polytypes of the vdW polar insulator α‐In2Se3, together with rapid, non‐destructive phase‐identification methods. Combined optical transmission and absolute reflectivity measurements, supported by DFT calculations, reveal distinct polytype‐dependent ...

Effect of Host Anisotropy on Phosphorescent Emitter Orientation and Light Outcoupling in OLEDs
Advanced Optical Materials, EarlyView.The orientation of the emissive transition dipole moment of a cage‐type Iridium complex can be tuned by the anisotropic alignment of the cohost material, which is expressed as the S$S$ parameter of the film. Thus, the external quantum efficiency of OLEDs can be further enhanced to reach values above 30%.
