摘要

通过化学气相沉积法(CVD)在云母基底上制备得到CsPbBr,3,微米棒，并使用扫描电子显微镜(SEM)、X射线衍射(XRD)对样品形貌和晶体结构进行表征。采用变温(10~290 K)荧光光谱研究了CsPbBr,3,激子发光的温度依赖特性。实验发现，在室温下CsPbBr,3,微米棒有两个发光峰，分别为位于2.357 eV、半宽为 52 meV的自由激子发光及能量位于2.298 eV、半宽为 73 meV 的束缚激子发光。从10 K开始，随着温度升高，自由激子的峰位能量单调蓝移，束缚激子的峰位能量在120 K 之前单调蓝移，其后趋于平缓。且激子峰半高宽随温度升高而逐渐增大。这种变温荧光特性主要是由于激子和纵向光学声子(LO)的相互作用引起的。本文有助于进一步理解CsPbBr,3,光物理特性，对未来高性能光电子器件研究具有指导意义。

Abstract

All-inorganic perovskite CsPbBr,3, microrods were prepared on mica substrates by chemical vapor deposition(CVD) method. The morphology and crystal structure of the samples were characterized by scanning electron microscopy(SEM) and X-ray diffraction(XRD). The CsPbBr,3, exciton luminescence was studied by temperature-dependent photoluminescence(PL) spectra from 10 K up to room temperature. The results reveal that there are two emission peaks at 10 K, which were attributed to exciton emission. The peak energy at 2.328 eV with a full width at half maximum(FWHM) of 20 meV was identified to free exciton recombination, and the peak energy at 2.313 eV with a FWHM of 29 meV was assigned to bound exciton emission. The peak energy of the free exciton monotonically blueshifts with the temperature increases, and so does the bound exciton until 120 K. Above 120 K, however, the peak energy of bound exciton tends to be flat when the temperature increases. Furthermore, the FWHM of the free exciton or bound exciton increases gradually. We have demonstrated these temperature-dependent photoluminescence properties are mainly due to the interaction between exciton and longitudinal optical phonons(LO). Our results could provide deeply understanding of intrinsic excitonic properties of CsPbBr,3, perovskites, which may be helpful to the development of high-performance optoelectronic devices.
