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 LixAlxSi1–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.

掺杂氧化钕的热稳定透明铝硅酸锂锡合金

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。
