Colloid systems modified by luminescent ions

are highly attractive for the design of new molecular architectures and adaptable for monitoring and visualizing soft drug delivery systems. This paper presents original results on the characterization of the self-organization process and the structure of vesicles formed by tetraethylene glycol monodecyl ether (C

Detailed characterization of surface activity, aggregation properties and microstructure of individual and mixed aggregates has been carried out based on surface tension, electron microscopy, small-angle X-ray scattering, dynamic light scattering analysis and fluorescence spectroscopy. The small-angle scattering results in combination with quantum-chemical calculations assume the multishell vesicle formation in C
