New BCN Fibres for Strong Ultraviolet and Visible Light Luminescence

Novel B₃CN₃ fibres with a special structure have been synthesized by a pyrolysis process. High-resolution TEM analysis shows that the as-prepared B₃CN₃ fibres can be described as a nanofibre-interweaved network. Strong photoluminescence at 370nm and 700nm from the as-prepared B₃CN₃ fibres are observed at room temperature, which suggests that B₃CN₃ is a promising ultraviolet- and visible-light-emitting material.
