Benchmarking Organic Photodiodes at the Noise Floor

Advanced Optical Materials, Volume 14, Issue 6, 9 February 2026.
A precise measurement framework based on a calibrated, ultra‐low‐noise automated setup with open‐source Python scripts enables accurate benchmarking of photodiodes. The unique combination of time‐dependent current measurement under dark conditions, followed by continuous‐wave faint illumination, facilitates reliable extraction of photocurrent near ...

Temperature‐Dependent Zinc Oxide Cathodoluminescence: Toward Compact Wavelength‐Tunable Solid‐State Photoionization Sources

Advanced Optical Materials, Volume 14, Issue 6, 9 February 2026.
A proof‐of‐concept of a thermally‐tunable cathodoluminescence‐based light source is demonstrated using a wide‐bandgap z‐cut ZnO crystal as anode, resulting in the ultraviolet (UV) emission peak shifting from 398 nm to ~409 nm (3.115‐3.032 eV). Our results establish the feasibility of a compact, field‐deployable UV source with potential for gas sensing ...

Simultaneous Multi‐Layer Stacking for Longer‐Wavelength Broadband Computed Tomography with a Carbon Nanotube Film Photo‐Thermoelectric Camera Sheet

Advanced Sensor Research, Volume 5, Issue 2, February 2026.
This work demonstrates broadband longer‐wavelength computed tomography reconstruction monitoring for multi‐layered composite 3D objects by developing a freely attachable large‐area‐view pixel‐integrated 2D camera sheet and multi‐wavelength photo‐sources.

Compact Optical Reservoir Computing via Luminescence Dynamics in Rare‐Earth Ions‐Doped Nanocrystals

Advanced Science, Volume 13, Issue 7, 3 February 2026.
A functionally compact optical reservoir computing platform is demonstrated using rare‐earth ion‐doped nanocrystals, whose intrinsic nonlinear luminescence dynamics and multi‐timescale metastable states provide nonlinear mapping and fading memory without bulky delays or resonant structures.

Photochemical Control of Perovskite Crystal Formation at Room Temperature

Advanced Science, Volume 13, Issue 9, 13 February 2026.
The authors demonstrate how ultraviolet (UV) light can enable the crystallization of two‐dimensional (2D) perovskite crystals that are otherwise difficult to grow using conventional thermal methods. These findings are supplemented with a detailed mechanistic description for the interaction of the UV irradiation with the perovskite precursor components.
