主　　题：electron beam perovskite quantum dots THz 

摘      要：This research argues that using an electron beam with high kinetic energy to pump perovskite quantum dots can significantly boost the efficiency of the low-frequency photon radiation ***,we measure the random lasing threshold and luminescence threshold of CsPbX_(3)films pumped by an electron ***,we simulate the spatial distribution of the electron beams in CsPbX_(3)*** with the above data,a low-frequency photon radiation conversion model based on the electron pumped perovskite quantum dots is *** could be a way to create a terahertz source with a high-power output or to multiply the terahertz power.
