采用热注射法制备了CsPbBr3/还原氧化石墨烯（RGO）纳米复合材料。采用透射电子显微镜（TEM）和x射线衍射仪（XRD）对合成的CsPbBr3/RGO纳米复合材料的晶体结构和形貌进行了表征。光致发光（PL）光谱表明，与纯CsPbBr3相比，CsPbBr3/RGO纳米复合材料表现出强烈的猝灭现象，这可能是光生空穴-电子对快速分离和转移的原因。此外，CsPbBr3/RGO纳米复合材料的PL衰减结果（τave= 4.52 ns）相对于相应的CsPbBr3纳米粒子（τave= 14.72 ns）相对较短，证明了CsPbBr3纳米粒子与石墨烯之间的电荷转移。同时，CsPbBr3/RGO纳米复合材料具有较强的光响应特性，在光电探测领域具有巨大的应用潜力。
CsPbBr3/Reduced Graphene Oxide (RGO) nanocomposites were prepared by a facile hot-injection method. The crystalline structure and morphologies of the as-synthesized CsPbBr3/RGO nanocomposites were characterized by transmission electron microscopy (TEM) and X-ray diffraction (XRD). The photoluminescence (PL) spectra indicated that CsPbBr3/RGO nanocomposites displayed strong quenching phenomenon compared with the pure CsPbBr3as the probably reason of the fast separation and transfer of the photogenerated hole-electron pair. Moreover, the PL decay results of the CsPbBr3/RGO nanocomposites (τave= 4.52 ns) was relatively shorter than that of the corresponding CsPbBr3nanoparticles (τave= 14.72 ns), demonstrated the charge transfer between the CsPbBr3nanoparticles and graphene. Meanwhile, an enhanced strong photoresponse was demonstrated by the CsPbBr3/RGO nanocomposites, which showed tremendous potential applications in the field of photoelectric detection.
