Overcoming spectral limits of perovskite photodetectors for the infrared region

InfoScience, EarlyView.
Infrared (IR) photodetectors are vital for modern optoelectronics, but traditional inorganic semiconductors face limitations in cost, processing, and bandgap tunability. This review provides a summary of advanced strategies to extend metal halide perovskites into the IR region, categorizing approaches into intrinsic material engineering, physical ...

Investigation of the laser fluence and wavelength dependence in surface‐assisted laser desorption/ionization mass spectrometry using gold nanoparticles

Rapid Communications in Mass Spectrometry, EarlyView.
Rationale Surface‐assisted laser desorption/ionization (SALDI) mass spectrometry (MS) builds on the use of nanostructured surfaces (e.g., coatings of colloidal nanoparticles) to promote analyte desorption and ionization. The SALDI process is believed to occur mainly through thermal processes, resulting from heating of the nanosubstrate upon absorption ...

More Photocatalysis With Less Light in Polar Semiconductors—The Role of Pyroelectric Fields

Small, EarlyView.
The work demonstrates that the modulated solar irradiation enhances the photocatalytic degradation of methyl orange on BaTiO3 despite reducing the photon flux by about 50%, resulting in a net overcompensation of catalytic efficiency. The effect arises from pyroelectric polarization near the phase transition, triggered by infrared heating of water ...

Mesophase Tunable Actuation of Ionic Thiol‐Acrylate Liquid Crystal Elastomers

Small, EarlyView.
Thiol‐acrylate ionic liquid crystal elastomers (iLCE) are developed with nematic and cybotactic mesophases and polydomain and monodomain genesis. The effect of genesis, mesophase, and microstructure on electroactuation was studied. ABSTRACT Electroactive polymers (EAPs) are envisioned to play a crucial role in next‐generation soft robotics for their ...

Spectral characterization of three wearable electronic ultraviolet radiation dosimeters

Photochemistry and Photobiology, EarlyView.
Excessive exposure to ultraviolet radiation poses significant public health risks, including DNA damage and skin‐related pathologies. Wearable electronic UV dosimeters enable accurate studies and quantification of solar UV‐radiation exposure on an individual level. Due to variations in the spectral distribution of solar radiation, the spectral mismatch

Device Simulation of Hole Transport in 233 nm Multiquantum Well AlGaN‐Based UV LED

physica status solidi (a), Volume 223, Issue 17, 9 September 2026.
Deep‐UV LEDs suffer from low hole injection efficiency. In this work, electro optical simulations of AlGaN DUV LEDs with 6, 12, and 21 quantum wells, emitting at 233 nm, reveal efficient inter‐well hole transport within the active multiple quantum well region. The data are consistent with experimental findings.
