Ratiometric Temperature Sensing through Alternating Current Electroluminescence
Advanced Optical Materials, EarlyView.Thermoresponsive alternating current electroluminescence (ACEL) is realized in ZnS microparticles with optimized Cu, Cl, and Co tri‐doping concentrations, exhibiting a blue‐to‐green emission band shift along with increasing temperature. Based on this behavior, an ACEL‐driven temperature sensing platform is developed for quantitative temperature ...
