Abstract :
Andersonʹs method of incorporation of C60 within the cages of a VPI-5 zeolite has been used as well as a chemical vapor deposition procedure. 129Xe NMR has confirmed that, starting from an organic solution of fullerene, C60, was actually incorporated into the molecular cages of the inorganic matrix. Thermal analysis and X-ray diffraction showed that the treatment does not affect the integrity of the crystalline structure of VPI-5. Photoluminescence experiments gave similar results as those already mentioned by other authors indicating the probable confinement effect of the inorganic matrix on the C60 isolated molecules.
