Laser spectroscopic studies of fullerenes, fullerene derivatives and erbium endohedral metallofullerenes

Fullerenes possess three-dimensional carbon-network structures with pentagonal and hexagonal rings as the building blocks and can be generated by a variety of methods including the most commonly used electrical-arc method. They have interesting material properties such as their optical non-linearity, catalytic activity, HIV-inhibition, superconductivity, photoconductivity, reversible multistage electrochemical reduction and oxidation, and have been studied extensively ever since their discovery; literature references literally cover all scientific fields.;We have measured the vibrational properties of C;The vibrational and vibronic frequencies of C;We have also studied the optical properties of the C;The erbium endohedral metallofullerenes have been synthesized and the optical properties have been measured by lock-in phase-sensitive spectroscopy, using a modulated CW Ar;Mixed fullerene samples can be characterized optically, using Site Selective Spectroscopy. By matching the individual high resolution spectra, the sample can be identified. In addition, the sample concentration can be obtained through the standard calibration curve and the accuracy can be ensured by multiple line calibration.
