The complexes [Ln(L)3(H2O)2]n (Ln=Nd, Sm or Eu; HL= 2-ethoxynicotinic acid) have been synthesised. Structural determinations reveal the complexes to have similar one-dimensional linear chain motifs, which can be further linked into two-dimensional layers via hydrogen bonding interactions. Their three-dimensional luminescence has also been studied.
The EuS–CdS heterostructured nanocrystals, which possess unique optical-magnetic properties, were synthesized by a co-thermal decomposition method.
