Synergistic Multi‐Strategy Engineering of Temperature‐Responsive Self‐Trapped Excitons in Tin‐Based Double Perovskite Nanocrystals Enables High‐Sensitivity Fluorescence Thermometry

open access: yesLaser &Photonics Reviews, EarlyView.
Bi3+‐doped Cs2SnCl6 nanocrystals are engineered to deliver highly temperature‐responsive self‐trapped exciton emission, achieving record thermal sensitivity at elevated temperatures. A temperature‐induced dual‐STE excited state landscape enables reversible thermochromism, while a dual‐parameter calibration combining fluorescence lifetime and CIE‐y ...

Harnessing Optical Limiting in Saturable Absorbers for Reconfigurable Spectral Engineering of Ultrafast Fiber Lasers

open access: yesLaser &Photonics Reviews, EarlyView.
Optical limiting in a nanomaterial‐polymer saturable absorber is harnessed as a functional intracavity degree of freedom, where pump‐controlled photothermal loss continuously reshapes the gain spectrum of rare‐earth ions, enabling non‐mechanical spectral engineering in an ultrafast fiber laser.

Field‐Cycling NMR Relaxometry in Tire Elastomer Science

open access: yesMagnetic Resonance in Chemistry, EarlyView.
Field‐cycling NMR relaxometry has established as an ideal tool to investigate multiscale polymer dynamics. Here, we review and discuss applications on elastomers and elastomer compounds of interest for the tire industry to obtain information on segmental dynamics and on polymer dynamics over different regimes as a function of chain length in polymer ...

Pulse Programme Considerations for Quantitative NOE Analysis

open access: yesMagnetic Resonance in Chemistry, EarlyView.
NOESY and ROESY spectra are frequently used to obtain interatomic distances in solution. Here, the performance of six routinely used pulse programmes is evaluated, with the number of quantified correlations and the accuracy of the NOE‐based distances being used as the main assessment criteria. ABSTRACT Accurate NOE/ROE‐based distance determination is a
