Harnessing Non-Boltzmann Steady States in Lanthanide Nanocrystals for Mid-Infrared Optoelectronics
This paper demonstrates that lanthanide nanocrystals can be driven into a non-Boltzmann steady state via mid-infrared irradiation to achieve ultra-low-power, ratiometric detection and room-temperature imaging across the 6.8–8.6 μm spectrum, overcoming the thermal equilibrium limitations of conventional approaches.
