Manifestation system to effect luminescence complexes of samarium (III) and gadolinium (III) in the presence of thenoyltrifluoroacetone and 1,10-phenanthroline. Increased intensity supersensitivity transition in luminescent ion complexing agent depends on the nature of the ligand and the formation of micro- and nanoparticles in the system. It is found that in the presence of tetracycline derivatives sensitized fluorescence intensity decreases.
