Abstract
Oxygen-sensitive photoluminescence intensity of a new combination of luminophore and matrix has been investigated for use in pressure sensitive paint applications. In consideration of oxygen permeability as well as optical transparency and structural stability, a fluorinated acrylate polymer is chosen as matrix in this study, where PtTFPP complex is dispersed and acts as luminophore responsible for the oxygen quenching. Processing conditions as to spin-coat films of the fluorinated acrylate doped with the PtTFPP are described. Pressure dependence of the photoluminescence emission of such spin-coat films is explained in connection with luminophore concentration, film thickness and types of substrate.
