Multimodal temperature sensing using Zn2GeO4:Mn2+ phosphor as highly sensitive luminescent thermometer
TL;DR: In this paper, a temperature sensing scheme was employed based on time-resolved technique with the help of an intensified charge coupled device (ICCD) and a fluorescent microscope, where the luminescence integral intensities ratio of obtained images for two time segments was calibrated to measure the temperature.
