The Role of Optical Centers in Neodymium‐Doped Calcium Fluoride: Optical Tagging and Nanothermometry in the Second Biological Window

open access: yesAdvanced Optical Materials, EarlyView.
Tuning excitation by only 6 nm unveils three distinct optical centres in CaF2:Nd3⁺,Y3⁺, each with unique spectral fingerprints. Some exhibit properties ideal for precise nanoscale temperature sensing. Abstract Nd3+ has been proposed for nanothermometry in biological media, as both its emission and excitation wavelengths fall within the regions of low ...

Dark‐State Guided‐Mode Resonance Sensors: Engineering Miniature Sensing Platforms

open access: yesAdvanced Optical Materials, EarlyView.
This research introduces compact guided‐mode resonance sensing using Gaussian‐beam‐induced symmetry breaking to excite dark states. The method generates high‐quality resonance signals in a small area, demonstrating a sensor with 128 micro‐cells and 200 nm RIU−1 sensitivity, showing potential for lab‐on‐chip and biosensing applications.

Ocean Sciences Section reorganizes

open access: yesEos, Transactions American Geophysical Union, 1995
On December 8, 1994, the AGU Council voted to approve a reorganization of the Ocean Sciences Section. The section has been subdivided to provide section members with a recognized voice in the affairs of the Union, recruit wisely for members to sit on the various committees, and evaluate Union policy statements for impact on the diverse membership, etc.

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.
