Semiconductor superlattice micro-/nanowires could greatly increase the versatility and power of modulating electronic (or excitonic, photonic) transport, optical properties. In this communication, we report growth of a semiconductor CdS/CdS:SnS(2) superlattice microwire through a coevaporation technique with microenvironmental control. Such a novel superlattice microwire can modulate the exciton and photons to show multipeak emissions with periods in a wide spectral range, which arise in the 1-d photon crystal and confined exciton emission. This system can be widely used in producing multicolor emissions, low-threshold lasing, study light-matter interaction, slow light engineering, and weak nonlinear optical devices.

超晶格 CdS/CdS:SnS2 微线的制备和周期性发射

半导体超晶格微/纳米线可以大大增加调制电子（或激子、光子）传输、光学特性的多功能性和功率。在本次通信中，我们报告了半导体 CdS/CdS:SnS(2) 超晶格微丝通过微环境控制的共蒸发技术的生长。这种新型超晶格微线可以调制激子和光子，以显示在一维光子晶体和受限激子发射中出现的宽光谱范围内的多峰发射。该系统可广泛应用于产生多色发射、低阈值激光、研究光-物质相互作用、慢光工程和弱非线性光学器件。
