Erbium-doped fullerenes Er@CC60) comprise an erbium ion or ions encased in a carbon cage and have very interesting optical properties. Here we present the results of our recent study on the production, isolation, and optical characterization of Er@C60.To optimize Er@C60 production, we used sublimation methods to separate the numerous metallofullerene molecules created in the reaction process. We then performed spectroscopic characterization of Er@C60 through its emission spectra, and performed fluorescence lifetime measurements of Er@C60 Finally, we built a tunable laser for optical measurements by using laser dye, a nitrogen pulsed laser source, a stepper motor, and LabView software.
