摘要
Nonstoichiometric Bi2O2.33 nanosheets have been synthesized via electrolytic corrosion of metal Bi. The novel route is neither template- nor catalyst-assisted, and is more simple than commonly used methods. Bismuth complex compound was used to increase bismuth concentration, and to enhance the diffusion rate of bismuth ions. The thicknesses of the as-obtained Bi2O2.33 nanosheets were 10-20 nm. One strong UV emission was detected in the high crystal quality Bi2O2.33 nanosheets at room temperature. The broad PL emission peak can be attributed to the near band-edge emission.
