Description
Summary:The authors report the first preparation of high-density ultrafine green-emitting wool-like BaCO sub(3) nanowires, having an average diameter of 18.5 nm, and an average crystallite size of 13.4 nm, by an electrospinning method with a subsequent two-step calcination approach. A possible vapor-solid interaction mechanism was proposed for the finest nanowires growth, where the reactive carbon dioxide vapors were generated during the static atmosphere ambient calcination and assisted oxidization nucleation at enhanced temperatures. Our work provides new insights into electrospun fiber diameter refinement viacontrolled calcination, and this simple post-electrospinning controlled strategy can be generally applied to other metal carbonate ultrafine NWs families.
