Abstract

The reported experiments have shown that electron irradiation of a thin silver film deposited on top of a silicate glass can lead to the formation of a sub-surface layer of molecular clusters in the glass, as evidenced by its increased optical absorption. This phenomenon was observed for the following irradiation parameters: electron energy E = 20 keV, full dose Q = 3.12 × 10¹⁷ or 6.24 × 10¹⁷ electrons/cm², current density j = 100–300 µA/cm². When the current density was raised to 1600 µA/cm², larger silver nanoparticles exhibiting visible-range plasmon resonance appeared even in the absence of thermal post-treatment.

未经后处理的电子束在硅酸盐玻璃中形成银分子团簇和纳米颗粒

报道的实验表明，电子照射沉积在硅酸盐玻璃顶部的薄银膜可以导致玻璃中分子团簇的亚表面层的形成，其光学吸收增加就是证据。当辐照参数为电子能量E = 20 keV，全剂量Q = 3.12 × 1017或6.24 × 1017电子/cm2，电流密度j = 100-300µA/cm2时，观察到该现象。当电流密度提高到1600µA/cm2时，即使没有进行热后处理，也会出现较大的等离子体共振银纳米颗粒。
