研究目的
Investigating the thermal sensing capability of Er3+,Yb3+ and Pr3+,Yb3+ doped LaF3 nanoparticles in the near-infrared (NIR) region for cryogenic temperature applications.
研究成果
The Er3+,Yb3+ doped LaF3 nanoparticles demonstrated excellent cryogenic thermometer properties with a high relative sensitivity in the NIR region, opening new avenues for advanced applications in very low temperature ranges. The Pr3+,Yb3+ doped LaF3 nanoparticles showed lower performance but still significant sensitivity in the cryogenic range.
研究不足
The study is limited to cryogenic temperature ranges (15 – 105K) and focuses on NIR sensing, which is less commonly reported compared to visible range sensors.
