Tapping Opportunity of Tiny-Shaped Particles and Role of Precursor in Developing Shaped Particles

Abstract

Metallic colloids are frequently used in industry and provide understanding of science at microns to nanometers scales along with their applicability for various technologically important applications. Present investigations deal with morphology and structure of gold, silver and their binary composition while processing certain amounts of their solutions in a newly designed process and tapping opportunities of developing tiny-shaped particles. At tuned ratio of pulse OFF to ON time and when gold solution was processed, several tiny-shaped particles developed at the solution’s surface. Such tiny particles exert force at the tip of each converting their structure of smooth element where steady-state immersing behavior directed them toward a common centre resulting into bind them for developing different geometric anisotropic shaped particles. Under identical parameters along with pulse time, processing solutions of silver nitrate and binary composition of chloroauric acid-silver nitrate result in the development of tiny particles having no specific shape where their assembling is under the mixed behavior of forces resulting in distorted particles. Elongation and deformation of gold and silver atoms while developing different structures are because of the plastically driven behavior of their electrons. In three-dimensional structures where atoms do not undergo transition to elongate, they retain the structure as it is, which is known as hcp structure or two-dimensional structure. Different nature of precursors along with morphology and structure of particles are discussed in this paper opening abundant avenues for research.
