Title

Spectroscopic Characteristics of Erbium-doped Fullerenes (Er@C60)

Presenter

Godwin Wang

Abstract

Erbium doped fullerenes (Er@C60) consist of 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. In order to optimize Er@C60 production, we used sublimation methods to separate the numerous metallofullerene molecules created in the reaction process. We performed spectroscopic characterization of Er@C60 through its absorption and emission spectra. We carried out fluorescence lifetime measurement of Er@C60, and built a tunable laser for optical measurement by using laser dye, a nitrogen pulsed laser source, a stepper motor, and a LabView Program.
