One-pot route for preparation of monodisperse CuInS2nanocrystals
一锅路线制备单分散纳米CuInS2
a b s t r a c t
Metal compoundSolar energy materialsChalcopyrite copper indium sulfide (CuInS2) nanocrystals (NCs) were synthesized by a one-pot route andcharacterized by XRD, TEM, HRTEM, EDS, UV–vis and SPS. The experimental results demonstrated that theCuInS2NCs synthesized by metal compound [Sn(acac)2Cl2] had good crystallinity, monodispersity andstoichiometric composition. The UV–vis absorption spectra showed the as-synthesized CuInS2NCs had fineabsorption in the visible light region and the energy band gap was estimated to be 1.58 eV. Moreover, themetal compound could improve the photoinduced charge separation and transfer effect of NCs based on theSPS study. The synthesis strategy developed in this work may be used as a general process for the synthesis ofpure or doped chalcogenide NCs, and may have great potential to be applied in high efficiency, yet low costphotovoltaic areas.
摘要
采用一锅法制备黄铜矿铜铟硫（CuInS2）纳米晶，利用XRD， TEM，HRTEM，EDS，UV-VIS和SPS对其表征。实验结果表明，利用金属化合物 [Sn（acac）2Cl2]合成的CuInS2纳米晶具有良好的结晶度，单分散性和化学计量组成。紫外 - 可见光吸收光谱表明合成的CuInS2纳米晶在可见光区域具有非常高的吸收系数，其能带隙大概是1.58eV。此外，金属化合物可以提高基于SPS研究的纳米晶体的光生电荷分离和转换效率。在这项工作中运用的合成策略可以被用于合成纯的或掺杂硫系纳米晶的一般过程，同时在高效率、低成本光伏领域具有很大的潜力。
