  Facile Solution‐Phase Synthesis of CuInSe ₂ Nanocrystals with Controlled Morphologies

  摘要：

  AbstractThe morphology of CuInSe2 nanocrystals plays a key role in their functional properties. Achieving controllable morphology is significant for studying their structures and novel properties. Here, CuInSe2 nanocrystals with a trigonal‐pyramidal shape have successfully been synthesized by a facile solution‐phase method. The nanocrystals were characterized by X‐ray diffraction (XRD), transmission electron microscopy (TEM), and X‐ray photoelectron spectroscopy (XPS), etc. The morphological evolution of the CuInSe2 nanocrystals was illustrated by tuning the injection temperature of oleylamine‐selenium (OAm‐Se). In addition, CuInSe2 nanocrystals with spherical and ellipsoidal shapes were also obtained when copper stearate was used as the copper precursor.

  Embodiments relate to methods of metal oxide nanocrystals preparation. In embodiments, a metal-organic precursor may be economically synthesized by reacting a metal with an organic acid. The organic acid may include an aliphatic chain longer than three carbon atoms. The metal may be In, Sn, Al, Ga, Zn, Cd, Sb, Bi, Ge, Mn, Ti, Nb, V, Cr, Mo, Fe, Y, Mg, Co, as well as mixtures thereof. Further processing of the metal-organic precursor (e.g. by pyrolysis, hydrolysis, or alcoholysis) produces metal oxide nanocrystals of desired characteristics. An metal-organic precursor of indium tin oxide (ITO) may be synthesized by reacting indium metal and tin metal with an organic acid having an aliphatic chain longer than three carbon atoms (e.g. stearic acid) at a temperature above 200° C. Further processing of the resulting metal-organic precursor yields ITO nanocrystals of regular shape, uniform size, and average diameter ranging of between about 1-500 nm.

  the Cu:In stoichiometric ratio in the nanocrystals was achieved. Amines were identified as catalytic reagents for the rapid oxidation of the CuInS(2) nanocrystals, which could be prevented by the formation of CuInS(2)/ZnS core/shell nanocrystals by a one-pot approach. CuInS(2)/ZnS core/shell nanocrystals also showed greatly improved optical properties, with photoluminescence quantum yield up to about

  Indium-doped zinc oxide nanocrystals (IZO NCs), capped with stearic acid (SA) of different sizes, were synthesized using a hot injection method in a noncoordinating solvent 1-octadecene (ODE). The ligand exchange process was employed to modify the surface of IZO NCs by replacing the longer-chain ligand of stearic acid with the shorter-chain ligand of butylamine (BA). It should be noted that the ligand-exchange percentage was observed to be 75%. The change of particle size, morphology, and crystal structures were obtained using a field emission scanning electron microscope (FE-SEM) and X-ray diffraction pattern results. In our study, the 5 nm and 10 nm IZO NCs capped with stearic acid (SA-IZO) were ligand-exchanged with butylamine (BA), and were then spin-coated on a thermal oxide ($SiO_2$) gate insulator to fabricate a thin film transistor (TFT) device. The films were then annealed at various temperatures: $350^\circ}C$, $400^\circ}C$, $500^\circ}C$, and $600^\circ}C$. All samples showed semiconducting behavior and exhibited n-channel TFT. Curing temperature dependent on mobility was observed. Interestingly, mobility decreases with the increasing size of NCs from 5 to 10 nm. Miller-Abrahams hopping formalism was employed to explain the hopping mechanism insight our IZO NC films. By focusing on the effect of size, different curing temperatures, electron coupling, tunneling rate, and inter-NC separation, we found that the decrease in electron mobility for larger NCs was due to smaller electronic coupling.

  研究人员在非配位溶剂 1-十八烯（ODE）中采用热注入法合成了掺铟氧化锌纳米晶体（IZO NCs），并用不同尺寸的硬脂酸（SA）封端。利用配体交换工艺，将硬脂酸的长链配体替换为丁胺（BA）的短链配体，从而改变了 IZO NCs 的表面。值得注意的是，配体交换率为 75%。利用场发射扫描电子显微镜（FE-SEM）和 X 射线衍射图谱结果获得了粒度、形态和晶体结构的变化。在我们的研究中，硬脂酸封端的 5 nm 和 10 nm IZO NC（SA-IZO）与丁胺（BA）进行配体交换，然后旋涂在热氧化物（$SiO_2$）栅极绝缘体上，制成薄膜晶体管（TFT）器件。然后在不同温度下对薄膜进行退火处理：$350^\circ}C$、$400^\circ}C$、$500^\circ}C$和$600^\circ}C$。所有样品都表现出半导体行为，并显示出 n 沟道 TFT。固化温度与迁移率有关。有趣的是，迁移率随着 NC 尺寸从 5 纳米到 10 纳米的增加而降低。Miller-Abrahams 跳变形式主义被用来解释我们的 IZO NC 薄膜的跳变机制。通过重点研究尺寸、不同固化温度、电子耦合、隧道速率和 NC 间分离的影响，我们发现较大 NC 的电子迁移率降低是由于电子耦合较小。
