Synthesis and study of yttrium aluminum garnets doped with neodymium and ytterbium

Ytterbium- and neodymium-substituted yttrium aluminum garnets were obtained by hydroxide coprecipitation and by the cryochemical method. A continuous series of solid solutions in the Y₃Al₅O₁₂ — Yb₃Al₅O₁₂ system and limited solid solutions (Nd _x Y_{1 ? x} )₃Al₅O₁₂ (0 ≤ x ≤ 0.19) were obtained. The synthetic methods used made it possible to reduce the synthesis temperature from 1800 to 950°C and to obtain more homogeneous and nanosized material.
