Suppressing Photothermal Artifacts in Flexible Fluorescent Fiber‐Optic Sensors for Accurate and Precise In Situ Temperature Monitoring

Advanced Science, EarlyView.
A partial‐inner‐cladding optical fiber (PICOF) is developed to suppress photothermal artifacts in fluorescent fiber‐optic thermometry by isolating the sensing layer from regions prone to photothermal effects. This structural design strategy enables high‐fidelity operation at elevated excitation power, achieving high accuracy (maximum absolute error ...
