A novel method for creating heterogeneous nanostructures based on differing melting temperatures has been developed, allowing for the fabrication of Au-Ag composite cross-structures via nanowelding technologies. In this process, Ag nanowires transform into ordered particles decorating the Au nanowire surfaces as the welding temperature increases due to the different melting points of Au and Ag. Various techniques, including scanning electron microscopy, focused ion beam imaging, and atomic force microscopy, are used to analyze the morphologies, cross-sections, and evolution of these 3D nanostructures. Compositions and binding energies are determined through X-ray diffraction and X-ray photoelectron spectroscopy, while transmission electron microscopy examines atomic structures. Additionally, the optical properties are assessed using spectrometry. Color filter electrodes are fabricated to evaluate their polarization properties, with sheet resistance measurements and light-emitting diode tests assessing color and brightness. This method has broad applications in fields such as biosensors, optics, and medicine. -Scientific Journal cover design by scapiens
