可调等离子体共振悬浮二维氧化钼薄片证明。2D配置产生大的去极化因子，并且超掺杂的存在产生可见光等离子体共振。超掺杂过程通过使用模拟太阳辐射还原半导体2D MoO3薄片来进行。所产生的等离子体共振可以通过掺杂水平和薄片的横向尺寸以及通过暴露于模型蛋白质来控制。
Tunable plasmon resonances in suspended 2D molybdenum oxide flakes are demonstrated. The 2D configuration generates a large depolarization factor and the presence of ultra-doping produces visible-light plasmon resonances. The ultra-doping process is conducted by reducing the semiconducting 2D MoO3 flakes using simulated solar irradiation. The generated plasmon resonances can be controlled by the doping levels and the flakes' lateral dimensions, as well as by exposure to a model protein.
