The glass transition zone in the system PbCl₂–PbF₂–PbO–SiO₂ was investigated; glasses, including those activated by neodymium, were obtained. The mechanical, optical, and spectral-luminescence properties of the glasses were investigated. It is shown that replacing fluorine with chlorine shifts the peaks of the luminescence and absorption lines to longer wavelengths.

Nd掺杂氯氟硅酸铅玻璃的合成与性能

研究了PbCl ₂ -PbF ₂ -PbO-SiO ₂体系中的玻璃化转变区；获得了玻璃，包括那些被钕激活的玻璃。研究了玻璃的机械、光学和光谱发光特性。结果表明，用氯代替氟会使发光和吸收线的峰向更长的波长移动。
