利用电子衍射研究了铟纳米颗粒在铝薄膜中的结构响应和熔化过程,分别对慢速加热和超快激光加热进行了研究。采用磁控溅射法制备纳米粒子。对于缓慢加热,铟纳米颗粒失去了它们的结构顺序低于铟的本体熔点约19 K。当纳米颗粒被冷却时,观察到显著的过冷。对于使用110 fs激光脉冲的超快加热,当从352 K加热时,纳米颗粒的子集在1.15- 1.40 Tm的范围内过热。铟纳米颗粒的时间响应超快激光激发被发现是各向异性的。
The structural response and melting of indium nanoparticles embedded in the ultrathin aluminum film were studied for slow thermal heating and for ultrafast laser heating using electron diffraction. The nanoparticles were prepared by magnetron sputtering. For slow heating, the indium nanoparticles lost their structural order ∼19 K below the bulk melting point of indium. Significant undercooling was observed when the nanoparticles were cooled. For ultrafast heating using a 110 fs laser pulse, a subset of the nanoparticles was superheated in the range of 1.15–1.40Tmwhen heated from 352 K. The temporal response of the indium nanoparticles to ultrafast laser excitation was found to be anisotropic.
