Improved Photothermal Heating of NaNdF<sub>4</sub> Microcrystals via Low-Level Doping of Sm<sup>3+</sup> for Thermal-Responsive Upconversion Luminescence Anti-Counterfeiting
This work reports the light-to-heat conversion (LHC) behavior of NaNdF<sub>4</sub> doped with Sm<sup>3+</sup>. Due to the cross-relaxation between Nd<sup>3+</sup> and Sm<sup>3+</sup>, the improved LHC is obtainable by introducing 5% Sm<sup>3+</sup>. When the laser power density is only 1.72 W/cm<sup...
