Polarization effects in photoluminescence spectra of Eu[sup 3+] ions in tris(dinaphthoylmethane) (monophenanthroline)europium(III) complex [abbreviated hereafter as Eu(dnm)[sub 3]phen] dispersed in stretched polyethylene (PE) reveal quasi-uniaxial alignment of the molecular complex, not present in the unstretched PE. The ligand field structure of Eu[sup 3+] [sup 5]D[sub 0]–[sup 7]F[sub 2] transition in the Eu(dnm)[sub 3]phen single crystal differs from that of a single molecule in stretched PE, indicating rearrangement of the organic ligands upon stretching. © 2002 American Institute of Physics.
