AgCu films were deposited on glass substrates by a sputtering system. Effects of accumulated energy on nanoparticle formation in pulse-laser dewetting of AgCu films were investigated. The results showed that the properties of the dewetted films were found to be dependent on the magnitude of the energy accumulated in the film. For a low energy accumulation, the two distinct nanoparticles had rice-shaped/AgCu and hemispherical/AgCu. Moreover, the absorption spectra contained two peaks at 700 nm and 500 nm, respectively. By contrast, for a high energy accumulation, the nanoparticles had a consistent composition of AgCu, a mean diameter of 100 nm and a peak absorption wavelength of 550 nm. Overall, the results suggest that a higher Ag content of the induced nanoparticles causes a blue shift of the absorption spectrum, while a smaller particle size induces a red shift.
通过溅射系统在玻璃基板上沉积了AgCu薄膜。研究了累积能量对AgCu薄膜脉冲激光去湿过程中纳米颗粒形成的影响。结果表明，去湿薄膜的性能取决于薄膜中累积能量的大小。对于低能量累积，两种不同的纳米颗粒分别呈米粒状/AgCu和半球状/AgCu。此外，吸收光谱分别在700nm和500nm处有两个峰值。相比之下，对于高能量累积，纳米颗粒具有一致的AgCu组成，平均直径为100nm，峰值吸收波长为550nm。总体而言，结果表明，诱导纳米颗粒中较高的Ag含量会导致吸收光谱发生蓝移，而较小的粒径会导致红移。
