發(fā)布時間:2018-09-08 07:20
【摘要】:近年來,非球形貴金屬納米顆粒因其結構與性質的獨特性,已越發(fā)受到研究人員的關注。其中,納米金三角片結構具有各向異性的表面能與表面等離子體共振特性,對發(fā)展新一代光子學與電子學器件具有重要意義。然而,相比普通球形納米粒子,納米金三角片的可控合成具有更大的難度。通過近十幾年的努力,無論是在提高納米金三角片的質量還是產量上,都有了顯著的進步�;诖�,本文分別從納米金三角片的合成方法、生長機理、分離純化以及其性質與應用等方面作系統(tǒng)介紹,希望該新材料能獲得更多的關注。隨著自組裝技術的發(fā)展,納米金三角片將是非常具有優(yōu)勢的一種組裝模塊,希望其能在化學、材料等領域發(fā)揮更大的作用。
[Abstract]:In recent years, nonspherical noble metal nanoparticles have attracted more and more attention due to their unique structure and properties. Among them, the nano-gold triangulation structure has anisotropic surface energy and surface plasmon resonance characteristics, which is of great significance for the development of a new generation of photonics and electronics devices. However, the controllable synthesis of gold triangles is more difficult than that of ordinary spherical nanoparticles. Through more than ten years' efforts, there has been remarkable progress in improving the quality and production of gold triangles. Based on this, the synthesis method, growth mechanism, separation and purification, properties and applications of the new material are introduced systematically in this paper. It is hoped that the new material will be paid more attention to. With the development of self-assembly technology, nano-gold triangulation will be a kind of assembly module with great advantages. It is hoped that it will play a more important role in chemistry, materials and other fields.
