A temperature-cancellation method of pressure-sensitive paint on porous anodic alumina using 1-Pyrenesulfonic acid

A temperature-cancellation method of pressure-sensitive paint is introduced. It uses an intermediate wavelength of two luminescent peaks, which are opposite in the temperature dependency. 1-Pyrenesulfonic acid is used as a luminophore to describe this method, which is applied onto a porous anodic alumina using the dipping deposition. The concentration of the luminophore solution is varied from 0.001 to 0.09 mM. It controlled the luminescent peak ratio, temperature cancelled wavelength, and pressure sensitivity. The cancellation wavelength is ranged from 429±13 to 493±23 nm. An optical band-pass filter with the temperature cancellation can be also provided by controlling the concentration.
