摘要：

Solid tin oxide (SnO2) nanospheres were fabricated via one-step hydrothermal treatment of tin foil in aqueous alkaline solutions at 180A degrees C. Based on the time-dependent experiments, the evolution behavior of Ostwald ripening is proposed to explain the formation mechanism. Besides a broad emission band at 600 nm, the SnO2 nanospheres, synthesized for 24 h, show an additional emission band at 490 nm that has a great sensitivity to the content of oxygen. Spectral examinations and analyses reveal that the two emission bands originate from the electronic states determined by the oxygen interstitials, intrinsic surface states, and oxygen vacancies.
