摘要
The effective preparation of rare-earth metallofullerenes is described. Graphiterod blended with rare earth oxide was used as starting material. The method consists of dou-ble are discharge, extraction with toluene in Soxhlet extractor and extraction with pyridine athigh temperature and pressure. The laser desorption time-of-flight mass spectrometry (LD-TOF MS) results showed that the more important factors influencing the formation of rareearth metallofullerenes appeared the conditions of their preparation and extraction and va-lence states of rare earth elements themselves.
