Advanced surface characterization of silver dots grown by vertical vapor phase growth method

This research successfully analyzed silver particles synthesized via the Vertical Vapor Phase Growth (VVPG) technique. Silver was deposited on quartz tubes and examined using scanning electron microscopy (SEM) energy-dispersive X-ray spectroscopy (EDS) to study morphology, elemental composition, surface roughness, and Fourier transform infrared spectroscopy (FTIR) to study functional groups in organic and inorganic materials. High-temperature heating transformed the irregularly distributed silver particles into smooth, spherical forms through spheroidization and Ostwald ripening. The particle sizes exhibited a range of surface textures, with height variations up to 65.42 µm and maximum height differences (Rz values) from 2.04 µm to 9.20 µm. These findings underscore VVPG's capability to produce silver particles with high purity and precise surface characteristics, making it a valuable technique for applications requiring stable and specific surface properties. The insights gained in this study offer potential applications in antimicrobial surfaces, medical devices, and precision electronic components.
