Longitudinal Assembly of Gold Nanorods on Various Templates for Optoelectronics

Different synthesis methods such as lithography, physical vapor deposition, layer-by-layer deposition, self-assembly, and laser irradiation are commonly used to deposit and arrange functional nanoparticles on a substrate. The properties of these hierarchically organized materials can be fine-tuned by controlling the shape, size, and crystallinity of the fundamental building blocks. However, achieving controlled organization of the building blocks in a desired architecture on a substrate remains a formidable challenge. This topic will discuss the most recent progress in self-assembly technique and challenges in achieving linear assembly of gold nanorods on a suitable substrate in one, two, or three dimensions and their impact on photonic applications.
