In order to isolate and purify an endohedral fullerene, a solvent washing was performed using toluene to concentrate the endohedral fullerene in a residual, but endohedral fullerene could not be efficiently purified because impurities other than the endohedral fullerene could not be sufficiently removed. Thus, the endohedral fullerene is isolated and purified by using a solvent such as chloronaphthalene or tetralin having a high solubility for the endohedral fullerene and concentrating the endohedral fullerene in the solvent. The endohedral fullerene isolated and purified by solvent extraction has a cluster structure where the endohedral fullerene is surrounded with empty fullerenes. Thus, this endohedral fullerene is highly stable and is a useful material applicable to various fields such as medical care and electronics.

A sensor whose size can be decreased without marring the performance and which can be installed in a narrow place, an electric device, and a method for easily manufacturing the electric device. By vacuum deposition of semiconductor on a columnar body or by applying a melt, solution, or gel of semiconductor to the columnar body, a coating of semiconductor is formed. Four insulating wires, a stripe band of the connected four insulating wires are wound around the columnar body. Then, one of the insulating wires is removed to form a copper wire in the vacant portion by copper vacuum deposition. Lastly, another insulating wire not adjacent to the copper wire is removed to form an aluminum wire in the vacant portion by aluminum vacuum deposition. By measuring the resistance between the copper and aluminum wires, the intensity of light striking the semiconductor can be determined.

A device and a method capable of producing induction fullerene with high yield are provided. Nitrogen gas being an object to be induced is introduced into a plasma flow producing chamber and a high-temperature flow forming chamber to form a high-temperature plasma flow consisting of nitrogen ions and electrons. A negative voltage is applied to a grid 105 to keep low electron energy in the high-temperature plasma flow. Then by making electrons collide with fullerene introduced from a fullerene sublimating oven 107, electrons are bonded to the fullerene and thereby the fullerene is ionized. A recovering cylinder 112 is disposed in an induction fullerene accumulating chamber so as to enclose a plasma flow. In this fullerene accumulating chamber, induction fullerene such as nitrogen-substitution hetero fullerene and nitrogen-included fullerene is produced and deposited in the recovering chamber 112.

With regard to a solid polymer based fuel cell, an electrolyte membrane for conducting proton between a fuel electrode and an air electrode is conventionally made from a material obtained by chemically modifying a hollow fullerene such as C60 by means of a proton dissociable group. However, this fuel cell poses a following problem: since the proton conductivity of the membrane is so low that the internal resistance of battery is increased, which, when big current is extracted, causes the electromotive force to be reduced. The electrolyte membrane is made of a material obtained by chemically modifying an endohedral fullerene doped with an atom whose electronegativity is equal to or higher than 3, by means of a proton dissociable group, or a material made from an endohedral fullerene doped with an atom whose electronegativity is equal to or lower than 1. The membrane ensures the improved proton conductivity and reduced internal resistance of battery, as compared with the conventional electrolyte membrane made from a material obtained by chemically modifying a hollow fullerene by means of a proton dissociable group.

Organic materials doped with alkali metal have been conventionally used for electron transport layers or electron injection layers which constitute light-emitting films in organic EL light-emitting elements which are used in display devices or illuminating devices. Such conventional organic materials involve problems such that a strict process control is required since the alkali metal is highly reactive and thus, likely to be formed into a hydroxide, such that the resulting light-emitting element or light-emitting device needs complete sealing, and such that life of the light-emitting element cannot be sufficiently long. The present invention uses an alkali metal-including fullerene or an organic material doped with an alkali metal-including fullerene for electron transport layers or electron injection layers which constitute light-emitting films in organic EL light-emitting elements. The alkali metal-including fullerene or the organic material doped with an alkali metal-including fullerene is not very reactive with moisture or other impurities in the atmosphere and thus, the process control thereof is easy. Furthermore, even with a simple sealing structure, the resulting light-emitting element can be sufficiently long life.

According to a containing-fullerene production method by the background art, containment target ions obtained by ionizing containment target atoms have been irradiated to empty fullerene within a vacuum vessel. This has resulted in a problem of a lower formation efficiency of containing-fullerene, in case of forming containing-fullerene which internally contains an atom larger than a six-membered ring of fullerene. It is thus devised to irradiate ions having larger diameters and masses to a fullerene film, simultaneously with irradiation of containment target ions thereto. Since ions having larger masses collide with fullerene molecules, the fullerene molecules are largely deformed and openings thereof are enlarged. Containment target ions are caused to enter cages of fullerene molecules, thereby increasing a probability of formation of containing-fullerene.
