In the present work we present preliminary research on producing of transparent polycrystalline ceramics. Samarium doped Yttrium oxide (1%, 3% and 5%) and Neodymium (1%) doped YAG (Y3Al5O12) translucent ceramics were fabricated by solid-state reaction. Commercial nanopowders was used as the starting materials: Sm2O3 (6μm) and Y2O2 (20-50 nm) for Sm3+: Y2O3 and α-Al2O3, Y2O3 and Nd2O3 (20-50 nm) for Nd3+: YAG. For the preparation of Nd3+: YAG, 0.5 wt% tetraethyl orthosilicate (TEOS) was use as sintering additive, and 1 wt % PEG (polyethylene glycol-400) as dispersant.
