The wavelength of pump light in white light mode is 400nm . 2 . the excitonic tunneling from cdznse qw to cdse quantum dots under resonant excitation was investigated using femtosecond pump - probe technology on the cdznse quantum well / cdse quantum dots structure 用飞秒脉冲泵浦-探测方法研究了cdse量子点znse cdznse量子阱结构在对cdznse量子阱的激子共振激发条件下激子在量子阱与量子点之间的隧穿。
