The effect of adding the oxide Nd₂O₃(0.1 – 3.0 mol.%) on the synthesis conditions, crystallization, and spectral properties of a thermostable Li₂O–Al₂O₃–SiO₂(LAS) sitall was studied. The introduction of up to 1 mol.% Nd₂O₃ no effect on the crystallization properties and the precipitation of the main crystalline phase of β-eucryptite-like solid solutions Li_xAl_xSi_1–xO₂, whereas increasing the Nd₂O₃ molar content to 3% significantly changes the nature of the crystallization of LAS glass. The obtained results show that the optical sitalls with near-zero CLTE, activated by neodymium ions right up to the level \( {N}_{\mathrm{Nd}}^{3+}\sim 4\times {10}^{20}{\mathrm{cm}}^{-3} \), can be regarded as a base for producing new light-emitting thermostable optical media.

研究了添加氧化物Nd ₂ O ₃（0.1 – 3.0 mol。％）对热稳定的Li ₂ O–Al ₂ O ₃ –SiO ₂（LAS）壁垒的合成条件，结晶和光谱性质的影响。引入高达1 mol％的Nd ₂ O ₃不会影响类β-锂霞石状固溶体Li _x Al _x Si _{1- x} O ₂的结晶性能和主晶相的沉淀，而增加Nd ₂ ö ₃摩尔含量为3％显着改变了LAS玻璃的结晶性质。获得的结果表明，由钕离子激活的具有接近零CLTE的光学便服一直达到\（{N} _ {\ mathrm {Nd}} ^ {3 +} \ sim 4 \ times {10} ^ {20} {\ mathrm {cm}} ^ {-3} \）可以看作是生产新的发光热稳定光学介质的基础。
