Up-convertion (UC) perovskite Er3 -doped PbTiO3 (Er-PTO) nanoparticles with green and red emissions were synthesized via the hydrothermal method. The UC properties were manipulated by adjusting the concentration of Er3 ions dopant. The green emission intensity was decreased as the doping concentration increased from 1% to 4% (mole fraction), whereas the red emission intensity was increased. The influences of Er3 ions on the temperature-sensing performance were further investigated. The results demonstrated that Er-PTO nanoparticles with doping 1% Er3 ions possessed a sensitivity of 3.1 × 10-3 K-1 at 475 K, presenting a high potential in optical heating devices.

相位测量偏折术(PMD)是一种结合光线反射原理和条纹相位编码的光学面形检测方法,具有设备简单、成本低廉、稳定抗干扰等优点。但传统的偏折术需要对透明元件后表面进行黑化或粗糙化处理,以避免后表面反射对条纹相位提取的干扰,过程中可能损伤光学表面。分析了PMD面形检测方法用于透明元件检测的数学模型,提出了一种基于多频条纹反射和谱估计算法的新型PMD——多频条纹偏折术,分离了透明元件前后表面反射信号。从数字
