摘要： The use, as markers of petroleum products, crude oils, biofuels or lubricants, of rare earth complexes or one of the constituents thereof chosen from rare earth ligands or salts, being capable of forming a rare earth complex after the addition of a developing solution. Preferably, the rare earth complex can be detected by time-resolved fluorescence. Also, a marking method and a method for detecting a rare earth complex as a marker of petroleum products, crude oils, biofuels or lubricants.
