Abstract:
The present invention relates to a silica particle comprising at least one complex of at least one lanthanide and of at least one ligand of formula (A) in which Z1, Z2 and Z3, which may be identical or different, each represent a group bearing an atom bearing a lone pair and/or a negative charge; R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11 and R12, which may be identical or different, each represent a hydrogen, an optionally substituted alkyl radical, an optionally substituted aryl radical, a halogen, a group —OR13 or a group —SR13, with R13 representing H, an optionally substituted alkyl group or an optionally substituted aryl group.
