Abstract
Bi2O3Chaplet-like Nanoparticles have been fabricated. Most of them have the average inner diameter of 200nm and the mean rim thickness of 20nm. Photoluminescence spectra of the nanorings at room temperature were investigated, which demonstrated that the rings present excellent optical properties. The influence of aging time on the morphology and structure of β-Bi2O3superstructures was also studied, indicating that the nanorings superstructures were transformed into nanoplates after a long aging time. The formation mechanism of the β-Bi2O3superstructures was also explored. This approach will be further extended to solvent-controlled fabrication of related minerals with novel complex superstructures.
