在这篇文章中，我们报道了在高温有机溶液中成功合成了具有高结晶度的准单分散In2O3纳米晶。纳米晶体的平均尺寸可以使用动态注入技术来调节。TEM和XRD研究表明，每个晶体都是单晶。光学测定表明，这些In_2O_3纳米晶的光致发光行为与体相不同，这可能是由于纳米晶中弱的量子限制效应和高结晶度的性质共同作用的结果。
In this communication, we report a successful synthesis of quasi-monodisperse In2O3 nanocrystals with high crystallinity in a high-temperature organic solution. The average size of nanocrystals can be tuned using a dynamic injection technique. TEM and XRD investigations indicate that each nanocrystal is a single crystal. The optical determination implies that the photoluminescence behavior of these In2O3 nanocrystals is different from that of the bulk, probably due to the combination of weak quantum-confinement-effects and the nature of high crystallinity in nanocrystals.
