Electronic energy transfer in the layered single crystal Sm[Ag$_{.5}$Au$_{.5}$(CN)$_{2}$]$_{3}$

The aim of this study is to examine the energy transfer between [Ag$_{.5}$Au$_{.5}$(CN)$_{2}$]$_{3}$ donors and the Sm$^{3+}$ acceptors with which they have been doped. The single crystals of [Ag$_{.5}$Au$_{.5}$(CN)$_{2}$]$_{3}$ have been doped with varying concentrations of Samarium. Energy transfer was characterized using steady-state excitation and emission spectra, lifetime measurements and time-resolved spectra. Data was obtained as a function of temperature between 77 K and room temperature. Strong luminescence is seen at all temperatures in the mixed-metal system, a contrast from the luminescence displayed in the pure gold and silver dicyanide donors.
