内容記述 |
Precise allocation of nano light-sources in photonic integrated circuits is essential for the development of next-generation optical technologies such as optical nano-circuits, quantum information processing, and quantum communication. However, controlling the position of such light sources is a challenging task. We here show that halide perovskite nanoparticle light sources can be generated at the desired positions by electron beam. We applied cathodoluminescence spectroscopy to CsPbBr3/Cs4PbBr6 composites produced by thermal evaporation and discovered that the intensity of green light emission from the CsPbBr3 nanoparticles increased with electron beam irradiation. Furthermore, by taking advantage of the high spatial resolution and controllability of the electron beam, we demonstrate nano-light source patterning on the film. |
