摘要

Previously, we measured temperature variations employing the spectral power and lifetime of the P-diketonate chelate europium (III) thenoyltrifluoroacetonate (EuTTA). The main goal of our work is to develop a system to convert infrared into visible radiation with EuTTA as the active medium of conversion. Here, we calibrate the fluorescence properties of EuTTA and confirm the reliability of the calibration. We detect black body radiation which serves to change the local temperature of the transducer, with our proposed system. When excited with UV radiation (365 nm), EuTTA fluoresces with its principal emission peak at 615 nm. The changes in spectral power, P_0(T), and mean lifetime, τ(T), of the fluorescence are related with the temperature change induced in the film due to the impinging black body radiation. We present the relative error and temperature differences obtained between the calculated (with calibration) temperature and reference measurements. Furthermore, we demonstrate that incoming radiation, which causes a temperature increase in the transducer (i.e. IR radiation), can be detected through the changes in EuTTA fluorescence parameters.
