Probe molecules of Eu(MAA)3Phen, Eu(Sal)_3Phen and Eu(CA)_3Phen were prepared by using europium oxide(Eu_2O_3), methacrylate(MAA), salicylic acid(HSal), cinnamic acid(HCA) and phenanthroline(Phen). A series of temperature sensitive paints(TSPs) were obtained by the polymerization of different probe molecules, methyl methacrylate(MMA) and the initiator of benzoyl peroxide(BPO). The structure, morphology, luminescence property of probe molecules and the temperature quenching property of TSPs were characterize...
