One-pot route for preparation of monodisperse CuInS2nanocrystals
一鍋路線制備單分散納米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
采用一鍋法制備黃銅礦銅銦硫（CuInS2）納米晶，利用XRD， TEM，HRTEM，EDS，UV-VIS和SPS對其表征。實驗結果表明，利用金屬化合物 [Sn（acac）2Cl2]合成的CuInS2納米晶具有良好的結晶度，單分散性和化學計量組成。紫外 - 可見光吸收光譜表明合成的CuInS2納米晶在可見光區(qū)域具有非常高的吸收系數，其能帶隙大概是1.58eV。此外，金屬化合物可以提高基于SPS研究的納米晶體的光生電荷分離和轉換效率。在這項工作中運用的合成策略可以被用于合成純的或摻雜硫系納米晶的一般過程，同時在高效率、低成本光伏領域具有很大的潛力。
