Fig. 3

Excitation (PLE) and emission spectra of 2-Eu and 3-Yb in solid (polycrystalline) state at different temperatures between 5 and 295 K. The PLE and PL spectra were recorded and excited at 580 and 350 (2-Eu), and 550 and 350 nm (3-Yb), respectively. The inserts show the integral emission intensity (normalized to unity) as a function of temperature.
