Spectroscopic characteristics of erbium-doped fullerenes
Erbium-doped fullerenes ([email protected]₆₀) 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 [email protected]₆₀.To optimize [email protected]₆₀ production, we used sublimation methods to separate the numerous metallofullerene molecules created in the reaction process. We then performed spectroscopic characterization of [email protected]₆₀ through its emission spectra, and performed fluorescence lifetime measurements of [email protected]₆₀. Finally, we built a tunable laser for optical measurements by using laser dye, a nitrogen pulsed laser source, a stepper motor, and LabView software.
