Microstructure and optical properties of Nd: YAG transparent ceramics with the addition of Lu 3+ ions
Source abstract
Abstract
The Nd:YAG transparent ceramics with addition of Lu3+ ions were fabricated by co-precipitation method and vacuum sintering. Pure YAG phases were obtained when Lu3+ ion content was kept under 4.5 at.-%. Lattice constant of polycrystalline ceramic with 0.8 at.-% Lu3+ calculated from XRD patterns was similar to that of YAG single crystal, and its fluorescent intensity arising from 4F3/2 → 4I9/2 transition of Nd3+ ions reached the maximum although the ceramic was opaque. The results indicated that Lu3+ ions under 1.5 at.-% relieved strains from lattice distortion and enhanced the fluorescent intensity.
