摘要

在平均直径为4 nm的液体中，通过加入不同浓度的溴化钾溶液将脉冲激光烧蚀合成的金纳米颗粒连接在一起。随着盐浓度的增加，颗粒尺寸显著增加，平均直径可达18 nm。我们通过原子力和电子显微镜表征研究了纳米颗粒的合并，也证明了在硅化基底上沉积烧结纳米颗粒是一种快速、简单、经济、节能的方法，与工业制造相关。

Low-Temperature Sintering of Colloidal Gold Nanoparticles by Salt Addition

Gold nanoparticles synthetized by pulsed laser ablation in liquid with a mean diameter of 4 nm were joined together by adding potassium bromide solution at various concentrations. By increasing the salt concentration, there is a significant increase of the particle size up to a mean diameter of 18 nm. We have studied the nanoparticle merging by using atomic force and electron microscopy characterizations, also demonstrating that it is possible to deposit sintered nanoparticles on silanized substrates in a fast, simple, cost-effective, energy-saving method with relevance in industrial manufacturing.

期刊介绍： ASM International''s Journal of Materials Engineering and Performance focuses on solving day-to-day engineering challenges, particularly those involving components for larger systems. The journal presents a clear understanding of relationships between materials selection, processing, applications and performance. The Journal of Materials Engineering covers all aspects of materials selection, design, processing, characterization and evaluation, including how to improve materials properties through processes and process control of casting, forming, heat treating, surface modification and coating, and fabrication. Testing and characterization (including mechanical and physical tests, NDE, metallography, failure analysis, corrosion resistance, chemical analysis, surface characterization, and microanalysis of surfaces, features and fractures), and industrial performance measurement are also covered
