Focusing on ternary I-III-VI colloidal nanocrystals (NCs) synthesized with precise control of the composition (from doping to ternary composition) and NIR fluorescence performance, monodisperse binary In -doped Ag S NCs and ternary AgInS NCs have been achieved successfully by facile low-temperature in situ conversion of colloidal Ag S nanoparticles. In ions were inserted into the crystal lattice of Ag S NCs at a relatively low temperature as dopant and ternary AgInS NCs were obtained at a higher temperature following a phase transition. These doped Ag S and AgInS 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.
专注于具有精确组成控制(从掺杂到三元组成)和近红外荧光性能的三元 I-III-VI 胶体纳米晶体 (NCs),通过简便的低温原位转化胶体 Ag 2 S 纳米粒子,成功地实现了单分散的二元 In 掺杂 Ag 2 S NCs 和三元 AgInS NCs。In 离子在较低温度下作为掺杂剂插入到 Ag 2 S NCs 的晶格中,在较高温度下发生相变得到三元 AgInS NCs。对于不同掺杂水平和晶体相演化的近红外光致发光发射的位置和强度,基于不同铟前体浓度的这些掺杂 Ag 2 S 和 AgInS NCs 进行了探索。
