An optical technique is proposed for the accurate calibration of pulsed high magnetic fields utilizing the magnetic field dependent photoluminescence (PL) properties in an Er(3+):YVO(4) single crystal at 80 K. Bright green PL emissions are excited by a 487.5 nm laser line and can be enhanced greatly by a magnetic field at certain field values (B(c)). Since the B(c)'s under 10 T are extremely stable for a given sample at a certain temperature, and the FWHM of the enhancement peaks are less than 0.9 T, an Er(3+):YVO(4) single crystal is proven to be a good candidate for pulsed high magnetic field calibration. The detailed processes and numerous advantages of the technique are presented in this work.
提出了一种利用 Er(3+)：YVO(4)单晶在 80 K 时的磁场依赖光致发光（PL）特性对脉冲强磁场进行精确校准的光学技术。通过 487.5nm 激光线激发明亮的绿色 PL 发射，并在特定磁场值（B(c)）下可以大大增强。由于在给定温度下给定样品的 B(c)值在 10T 以下非常稳定，并且增强峰的半峰全宽（FWHM）小于 0.9T，因此 Er(3+)：YVO(4)单晶被证明是脉冲强磁场校准的良好候选材料。本工作介绍了该技术的详细过程和诸多优点。
