Abstract

Photoluminescence spectroscopic measurements have allowed the acquisition of high resolution spectra at low temperature for the endohedral metallofullerenes, Er2@C82 (isomer I) and Er2C2@C82 (isomer I). The characteristic emission in the 1.5-1.6 μm region corresponds to the 4I13/2 (m) → 4I15/2 (n) transitions of the Er3+ ion for both molecules. The emission arising from Er2C2@C82 (I) appears acuminated (narrow lines that taper to a point) when compared with that of Er2@C82 (I). The Er2C2@C82 (I) emission linewidths are comparable to those found in crystals, making this molecule of interest for applications where accessible, well-defined quantum states are required.
