In this paper, the effect of doping phosphorus in a borosilicate glass matrix to improve the solubility of Mo was investigated by X-ray diffraction (XRD), Raman, and solid-state nuclear magnetic resonance (NMR) spectroscopy, and the effectiveness of Na content on P species inhibiting the growth of the crystallization of Mo was assessed. The results indicate that phosphate-doped borosilicate glass can host 4 mol% of Mo, and that such a borosilicate glass matrix could only accommodate 1 mol% of Mo without phosphate doping. The effectiveness of phosphorus may be correlated with the Na content in borosilicate glass, and a high Na content borosilicate glass matrix requires more P doping to accommodate Mo. In addition, incorporating large amounts of P can compromise the aqueous durability of the glass matrix.
本文通过X射线衍射（XRD）、拉曼光谱和固态核磁共振（NMR）光谱研究了在硼硅酸盐玻璃基体中掺杂磷对提高Mo溶解度的影响，并评估了Na含量对P物种抑制Mo结晶生长的有效性。结果表明，掺磷硼硅酸盐玻璃可容纳4 mol%的Mo，而未掺杂磷的硼硅酸盐玻璃基体仅能容纳1 mol%的Mo。磷的有效性可能与硼硅酸盐玻璃中的Na含量相关，高Na含量的硼硅酸盐玻璃基体需要更多的P掺杂才能容纳Mo。此外，大量掺入P会损害玻璃基体的水耐久性。
