Antimony nanocrystals (Sb NCs) are of interest in energy storage, catalysis and cancer therapy for its special physical, chemical and biomedical properties. However, methodology challenges still remain in preparation of colloidal Sb NCs, due to the restricted reaction solution systems, high temperature and time costing for common routes. Herein, size controllable colloidal Sb NCs were continuously prepared by pulsed laser ablation of Sb target in different solvents, owning to the metal nanodroplet explosive ejection and thermal evaporation mechanisms. These well dispersed and stable Sb NCs showed excellent photothermal property in the near-infrared-II window.
锑纳米晶体(Sb NCs)因其特殊的物理、化学和生物医学特性,在能量存储、催化和癌症治疗领域备受关注。然而,由于受限的反应溶液体系以及常规方法制备时高温且耗时,在制备胶体状Sb NCs方面仍存在方法学挑战。在此,通过在不同溶剂中对Sb靶材进行脉冲激光烧蚀,连续制备出尺寸可控的胶体状Sb NCs,这归因于金属纳米液滴的爆炸式喷射和热蒸发机制。这些分散良好且稳定的Sb NCs在近红外-II窗口展现出优异的光热性能。
