论文摘要
在这项工作中，我们观察到等离子体诱导的热电子提取在二氧化物氧化物纳米晶体和单层钼二硫化物之间的异质结中。我们在1750 nm的样品中研究样品，在1750 nm的样品中，浓度的含氧氧化物氧化物纳米晶体的强烈局部等离子体表面谐振在哪里以及单层钼二硫化物不吸收光。通过在1750 nm处的激发，我们观察到可见范围内二硫化钼的激发特征，靠近二硫化钼的激子。这种现象可以归因于等离子体激发后的二氧化物氧化物纳米晶和单层钼之间的电荷转移。这些结果是实施近红外等离子材料以进行光转换的第一步。
In this work, we observe plasmon induced hot electron extraction in a heterojunction between indium tin oxide nanocrystals and monolayer molybdenum disulphide. We study the sample with ultrafast differential transmission exciting the sample at 1750 nm where the intense localized plasmon surface resonance of the indium tin oxide nanocrystals is and where the monolayer molybdenum disulphide does not absorb light. With the excitation at 1750 nm we observe the excitonic features of molybdenum disulphide in the visible range, close to the exciton of molybdenum disulphide. Such phenomenon can be ascribed to a charge transfer between indium tin oxide nanocrystals and monolayer molybdenum disulphide upon plasmon excitation. These results are a first step towards the implementation of near infrared plasmonic materials for photoconversion.
