Xe distribution in Xe-ion implanted NaCI crystal

Former experimental results show that solid-state alkali-Xe cluster could be formed in xenon-ion-implanted alkali halide crystal. This kind of cluster makes solid state alkali metal-xenon nano-materials potential candidates for preparing UV micro-laser matrix. By means of Rutherford Backscattering Spectrometry (RBS) and TRIM codes, Xe atom distributions are studied in this paper. The results show that Xe was found at a depth of around 250 nm. As xenon concentration increased, the number of metallic Na colloids increased as well. These metallic Na colloids were found in SEM images of our irradiated samples, and the formation of solid-state NaXe clusters in NaCl implanted by ¹²⁹Xe has been used to explain the results in this paper.
