Bi2O2.33 nanoflowers with pure phase were directly prepared via a solvothermal route. The magnetism behavior of the product was investigated, and the data clearly revealed the room-temperature ferromagnetism of the synthetic sample. This nonstoichiometric bismuth oxide should be the diluted magnetic semiconductors (DMSs). XPS measurements showed that the room-temperature ferromagnetism might be derived from the presence of Bi2+ in the structure. The achievement of the nonstoichiometric Bi2O2.33 DMSs might pave the way for a new understanding of the underlying ferromagnetic mechanism in DMSs materials.
