Synthesis and characterization of nanocomplexes of Eu(III) and Er(III) coordinate with 2(4-clorophenil)-3-phenyl-1,3,4-thiadiazoleo-5-tiolate mesoionic

The solids achieved in nanometric scale have been demanding scientific and technological interest due to the significant alterations in physical and chemical properties observed in such kind of materials, potentializing their technological applications. The nanocomplexes produced by lanthanide ions...
