A Dual‐Emissive DNA‐Templated Silver Nanocluster with Near‐Infrared I and II Emission

open access: yesAdvanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
This study presents a dual‐emissive DNA‐stabilized silver nanocluster with a nanosecond‐lived NIR‐I emission band and a microsecond‐lived NIR‐II emission band. Mass spectrometry establishes that the nanocluster has molecular formula (DNA)2[Ag17]11+. DNA sequence variations reveal critical nucleobases for stabilization, and modifications at the DNA 5 ...

Advanced Image‐Integrated Smart Windows using Printed Electrochromic Polymer‐Dispersed Liquid Crystal Droplets

open access: yesAdvanced Optical Materials, EarlyView.
This study presents printed image‐integrated smart windows that simultaneously control color and transmittance using electrochromic polymer‐dispersed liquid crystals (ECPDLCs). By optimizing the electrochromic LC composition and refining the drop‐on‐demand printing process, precise image integration and dynamic optical control are achieved.

Excitonic Anisotropy in Single‐Crystalline 2D Silver Phenylchalcogenides

open access: yesAdvanced Optical Materials, EarlyView.
Using a combination of ab initio theory and optical micro‐spectroscopy, in‐plane anisotropy of multiple delocalized excitons in 2D silver phenylchalcogenides (AgEPh; E = S, Se, Te) is predicted and characterized. Cryogenic reflectance micro‐spectroscopy further reveals the fine structure of excitonic bands in AgSePh.

Monolithically Integrated Fourier Injected REsonator (FIRE) for Passive Coherent Laser Combination

open access: yesAdvanced Photonics Research, EarlyView.
Semiconductor diode‐based Fourier Injected REsonator (FIRE). The concept of free space FIRE, formerly known as the self‐Fourier cavity, is demonstrated for the first time on a chip‐scale device. A very high laser array coherence (97.7% fringe visibility), corresponding to single out‐of‐phase supermode operation, is reported.

Integration of Soft‐Robotics and Deep Learning to Assess the Coordinated Biosonar Emission and Reception Dynamics in Hipposiderid Bats

open access: yesAdvanced Robotics Research, EarlyView.
Combining a biomimetic soft‐robot with deep‐learning data analytics sheds light on a unique peripheral dynamics seen in the biosonar system of bats: Bats modulate their ultrasonic biosonar signals upon emission as well as reception with variable, yet highly coordinated motion patterns of their noseleaves and pinnae.
