Temperature-sensitive paint, useful for measuring two-dimensional temperature distributions in a wind tunnel, comprises a binder to form a polyurethane matrix and a fluorophore of europium complex dispersed in binder
Temperature-sensitive paint comprises: a binder to form a polyurethane matrix; and a fluorophore dispersed in the binder, where the excitation of the fluorophore to emit the fluorescent light is quenched depending on the temperature, and the fluorophore is an europium complex including (tris(1,3-dithiophene-2-yl-propane-1,3-dionato)-europium(III)) or (europium(III)-tris-[3-(heptafluoropropylhydroxymethylene]-d-camphorate). The binder forms an acrylic-urethane polymer matrix.
