基于荷能离子与固体相互作用特点,提出了一种新的制备光致发光材料的方法-- 高能重离子辐照. 用这种方法研究了SiO2薄膜的光致发光特性,发现高能84K r和40Ar离子辐照可在注碳SiO2薄膜样品中产生强的蓝-紫光发射带,掺杂碳增强了辐照样品的发光特性.

A novel method, high energy heavy ion irradiation, was proposed to pr oduce light-emitting structures. It was used in studying photoluminescence properties from C-doped SiO2 films.
