研究了x Na2O - yAg2O - zAl2O3 - (1- x- y- z)P2O5玻璃中Ag粒子的析出。室温条件下，氮离子辐照可提高银相的体积分数。在距离玻璃表面80 nm处观察到离子辐照增强的沉淀。在没有Na2O （x=0）的情况下，Ag被氮离子通量选择性溅射。在含Na2O的玻璃中，辐照诱导的Ag去除被抑制，析出物的数量增加。辐照玻璃的三阶非线性光学磁化率χ(3)估计在5.5 ~ 8.8×10-7 esu之间。较高的磁化率与大量的银析出相一致。辐照诱导的Ag2O和Na2O的分解是一种可能的沉淀形成机制。
The precipitation of Ag particles in x Na2O– yAg2O– zAl2O3–(1- x- y- z)P2O5 glasses was studied. The volume fraction of quantum-size Ag precipitates was enhanced by nitrogen ion irradiation at room temperature. Ion-irradiation-enhanced precipitation was observed up to a distance of 80 nm from the glass surface. In the absence of Na2O (x=0), Ag was selectively sputtered by the nitrogen ion flux. In glasses containing Na2O, irradiation-induced Ag removal could be suppressed and the amount of precipitates increased. The third-order nonlinear optical susceptibility, χ(3), of the irradiated glasses was estimated to range from 5.5 to 8.8×10-7 esu. The large susceptibilities are consistent with the large amount of Ag precipitates. The irradiation-induced decomposition of Ag2O and Na2O is one possible precipitant-forming mechanism.
