Temperature-dependent photoluminescence study of ErSc2N@C 80 and Er2ScN@C80 fullerenes
The photoluminescence study of the Er3+ ion in ErSc 2N@C80 and Er2ScN@C80 fullerenes in the temperature range of 5 K to 80 K is presented. New emission peaks are observed for both fullerenes above 20 K. These peaks arise from thermally populated crystal-field levels of the excited state. An anomalou...
