Combined pressure and temperature sensor using pressure- and temperature-sensitive paints

In pressure-sensitive paint (PSP) measurements, pressure is deduced from the luminescence intensity of PSP. Since the intensity depends not only on pressure but also on temperature, PSP results have to be compensated by the surface temperature; thus, we combined temperature-sensitive paint (TSP) with PSP for the compensation. PtTFPP and CdSe/ZnS were adopted as pressure and temperature sensitive luminophores, respectively. In this paper, we report the pressure and temperature sensitivities and the photostability of the combined sensor around an atmospheric pressure and room temperature.
