A triple-layered luminescent polymer coating was prepared to simultaneously detect both oxygen and temperature upon the coating. The coating was composed of an oxygen and a temperature sensory layer based on platinumporphyrin (PtTFP) and ruthenium phenanthroline (Ru(phen)) dye molecule, respectively. The temperature-sensitive Ru(phen) was dispersed in gas-barrier polyvinyl alcohol as the first layer, which was further coated with a water-proofing fluorine-containing polymer. The oxygen sensory layer composed of the oxygen-sensitive PtTFP and high oxygen-permeative poly(1-trimethylsilyl-1- propyne) was coated as the third layer. The two luminescences were separately monitored: the oxygen partial pressure and temperature in the range of 0-21 kPa and of 25-120 8C were successfully detected.
