Firstly, and by using chitosan and PS-co-P4VP as polymeric supports, macromolecular complexes of type chitosan LnCl(3) and PS-co-P4VP center dot LnCl(3) were prepared. These macromolecular complexes were treated in solid state at 800 degrees C under air, leading to the corresponding LnOCl or Ln(2)O(3) materials (Ln = Eu, Nd) with moderate to good yields. The nature of the as-prepared lanthanide materials (LnCl and/or Ln(2)O(3)) is strongly influenced by the polymeric template (i.e., chitosan or PS-co-P4VP), the lanthanide salt precursor, and the polymer/lanthanide molar ratio. Thus, when chitosan center dot LnCl(3) and PS-co-P4VP center dot EuCl3 are used as macromolecular precursors, a mixture of crystalline phases o f both EuOCl and Eu2O3 are obtained. However, when chitosan center dot NdCl3 and PS-co-P4VP center dot NdCl3 are used, a sole pure crystalline phase of NdOCl is obtained. The nanostructured lanthanide materials were characterized by means of XRD (X-ray diffraction of powder), SEM, EDS, TEM, and HRTEM. The luminescent spectra of the as-prepared EuOCl/Eu2O3 mixture materials show an emission pattern whose intensity is strongly influenced by the nature of the polymeric precursor, as well as on the metal/polymer molar ratios.
