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.
