Abstract:
Low temperature photoluminescence (PL) and photoluminescence excitation (PLE) spectroscopy of high purity ErSc2N@C80 and Er2ScN@C80 fullerenes reveal at least two metastable configurations of the Er3+ ion within the cage, consistent with previous observations from x-ray diffraction. Using PLE measurements at a number of different emission wavelengths we have characterized the ground state, I15∕24, and the first excited state, I13∕24, of the various Er3+ configurations and their crystal-field splitting. We present detailed energy level diagrams for the ground and excited states of the two dominant configurations of ErSc2N@C80 and Er2ScN@C80.
