One of the unique properties of fullerene molecular is the possibility to contain atoms and molecules inside the carbon cage. “Endohedral” is used for fullerene with species incorporated in the carbon cage. Endohedral carbon structures are the new class of nanosized objects with unique chemical and physical properties and advanced applications. A number of important tasks of electronic and aerospace engineering may be solved by investigation of endohedral metallofullerenes properties and their application, for example, for nanostructured super absorbent coatings and new aerotechnics. In this paper the method for fast determination of endohedral metallofullerenes content at the fullerene mixture which was synthesized with metal oxide addition is presented. The methods of mass spectroscopy and atom emission element analysis are determined at the technique. By the method of mass spectroscopy the type of endohedral metallofullerenes with atom-guest is registered and by the method of emission spectroscopy the quantity of that element which contained at the fullerene mixture. The technique may be used for rapid determination of endohedral metallofullerenes weight percents at the fullerene mixture in case if only one type of endohedral metallofullerenes is in fullerene mixture, and of endohedral metallofullerenes average content if there are different types of endohedral metallofullerenes at the fullerene mixture. The effective synthesis method, extraction and analysis of endohedral metallofullerenes are demonstrated on the example of Gd@C82.
Keywords: endohedral metallofullerenes atomic, gadolinium, emission analysis.
