Microstructure and optical properties of AgCuAl medium entropy films with nanoparticles induced by pulsed-laser dewetting

H. K. Lin et al.

Summary: The study demonstrates that AgCuAl equimolar complex concentrated alloy thin films can form nanoparticles through dewetting with a NIR pulsed-laser system. These nanoparticles mainly consist of Ag and Cu, exhibit local surface plasmon resonance peaks, and their size and wavelength can be controlled by adjusting the energy density.

Optical properties of segmented Ag-Au wire at single particle level studied with a home-built micro-spectrometer

Bhanu B. Neupane et al.

Summary: Nanomaterials with hetero-metallic junctions are being studied for various applications. A study on segmented Au-Ag wires revealed enhanced radiative properties at the bimetallic junction, making them potentially useful as imaging probes or single particle sensors. Excitation with two-photon UV light resulted in luminescence peaks and intense second harmonic generation signals.

Effects of Accumulated Energy on Nanoparticle Formation in Pulsed-Laser Dewetting of AgCu Thin Films

H. K. Lin et al.

Summary: The study found that under low energy accumulation, AgCu films formed nanoparticles with different shapes and compositions, resulting in different absorption spectra. However, under high energy accumulation, the nanoparticles had consistent compositions, regular sizes, and absorption wavelengths closer to each other.
