Characteristic Evaluation of Chameleon Luminophore Dispersed in Polymer
A temperature-sensitive paint (TSP) using a chameleon luminophore [Formula: see text] is proposed. The chameleon luminophore was dispersed in isobutyl methacrylate polymer in a toluene solvent to fix it on a sample coupon. Temperature and pressure sensitivities of the chameleon luminophore-based TSP...

description | A temperature-sensitive paint (TSP) using a chameleon luminophore [Formula: see text] is proposed. The chameleon luminophore was dispersed in isobutyl methacrylate polymer in a toluene solvent to fix it on a sample coupon. Temperature and pressure sensitivities of the chameleon luminophore-based TSP were measured using a spectrofluorophotometer. The emission for each wavelength was confirmed to be dependent on the temperature and pressure. The temperature and pressure sensitivities of the TSP were 0.81–2.8%/K and 0.08–0.12%/kPa, respectively. Higher temperature sensitivity can be obtained using the ratio of emissions from the two lanthanide ions, [Formula: see text] and [Formula: see text]. The temperature sensitivity when using the ratio of the emission intensities at 616 nm derived from [Formula: see text] and at 545 nm derived from [Formula: see text] was 3.2%/K, which was the highest value in the present study. In addition, the pressure sensitivity for the case using the ratio of the emission intensities at 616 and 545 nm was [Formula: see text] /kPa. Higher temperature sensitivity and lower pressure sensitivity than that with a single wavelength can be achieved using the ratio of the emission intensities at the two peak wavelengths derived from [Formula: see text] and [Formula: see text]. |
