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 ...

Quantum Emitters in Rhombohedral Boron Nitride

open access: yesAdvanced Optical Materials, EarlyView.
Rhombohedral boron nitride (rBN) is an emerging wide‐bandgap van der Waals (vdW) material with strong second‐order nonlinear optical properties. In this work, optically‐addressable spin defects and single‐photon emitters (SPEs) are fabricated deterministically in rBN.

C2LI: Enhancing Structural Color Sensing and Imaging via Complementary Color Laser Illumination

open access: yesAdvanced Optical Materials, EarlyView.
This article introduces complementary color laser illumination (C2LI) and demonstrates it to be an effective approach for engaging the visual system to enhance perceptual sensitivity and chromatic contrast. This enhances a human user's ability to detect subtle differences in sample or medium characteristics, enabling novel applications in colorimetric ...
