Focusing on ternary I‐III‐VI2 colloidal nanocrystals (NCs) synthesized with precise control of the composition (from doping to ternary composition) and NIR fluorescence performance, monodisperse binary In3+‐doped Ag2S NCs and ternary AgInS2 NCs have been achieved successfully by facile low‐temperature in situ conversion of colloidal Ag2S nanoparticles. In3+ ions were inserted into the crystal lattice of Ag2S NCs at a relatively low temperature as dopant and ternary AgInS2 NCs were obtained at a higher temperature following a phase transition. These doped Ag2S and AgInS2 NCs based on different indium precursor concentrations were explored with respect to the position and intensity of the near‐infrared photoluminescent emission at different doping levels and crystal phase evolution.

从铟掺杂的Ag2S到AgInS2纳米晶体：胶体Ag2S纳米颗粒的低温原位转化及其NIR荧光
专注于精确控制组成（从掺杂到三元组成）和NIR荧光性能的三元I-III-VI 2胶体纳米晶体（NC），单分散In 3+掺杂的Ag 2 S NC和三元AgInS 2 NC具有二元分散态胶体Ag 2 S纳米粒子的便捷低温原位转化成功实现了这一目标。在3+离子在较低温度下被插入到Ag 2 S NCs的晶格中，这是由于在相变之后在较高温度下获得了掺杂剂和三元AgInS 2 NCs。这些掺杂的Ag 2 S和AgInS 2 就不同掺杂水平和晶相演化情况下近红外光致发光发射的位置和强度，探索了基于不同铟前体浓度的NCs。
