Synthesis and photoluminescence of the solid phases of the binary system of mixed-ligand Eu(III) and Tb(III) dithiophosphinate complexes

Abstract

Solid phases of the [Eu(Phen)(i-Bu2PS2)2(NO3)]–[Tb(Phen)(i-Bu2PS2)2(NO3)] binary system are synthesized. The results of X-ray diffraction phase analysis and photoluminescence measurements allow the synthesized isostructural phases to be classed with substitutional solid solutions. The photoluminescence measurements revealed Tb(III)→Eu(III) energy transfer which induces Eu3+ luminescence.
