Unlocking the Potential of Ni2+ and Ni2+-Cr3+ Synergy for Bifunctional Pressure and Temperature Optical Sensing
This study introduces a novel Ni2+-Cr3+ synergistic platform that achieves record-high, fully decoupled simultaneous optical sensing of pressure and temperature under extreme conditions by leveraging time-gated dual-ion lifetime and single-ion luminescence strategies to eliminate cross-sensitivity.
