Abstract

The purpose of this research was to increase the emission intensity of select lanthanide cations through dual donor sensitization. Novel isostructural compounds were synthesized from the respective lanthanide nitrate, silver dicyanide or gold dicyanide, and terpyridine solutions, with products of general formula Ln(CI5HIIN3)(N03)2(H20)(M(CN)2), where Ln= Eu, Gd, Tb, Dy, Ho, Er, Yb. and M= Ag, Au. The crystalline products were characterized through X-ray diffraction and absorbance spectra were obtained through UV-Vis spectroscopy. Photoluminescence tests indicate that cooperative sensitization was achieved from both donor ligands, increasing the intensity of lanthanide emission through indirect sensitization.
