我们首次成功地将Bi2SrTa2O9剥离成单纳米片。AFM测得的纳米片厚度约为1.3 nm。在室温下285nm激发下，纳米片本身显示出可见的蓝色发光。纳米片的发光性能对表面环境的变化非常敏感，如H+和/或OH-的吸附。
We succeeded in the exfoliation of Bi2SrTa2O9 to a mono-nanosheet for the first time. The thickness of the nanosheet obtained by AFM measurement was about 1.3 nm. The nanosheet itself showed visible blue luminescence under excitation at 285 nm at room temperature. The luminescence property of the nanosheet was largely sensitive to the change in the surface environment such as adsorption of H+ and/or OH-.
