Tm:Y2O3 transparent ceramics were obtained by sintering at 1850 °C for 25 h. Effect of different disper-sants and binders to the quality of ceramics were studied. Polyethylene glycol (PEG) was used as disper-sant. Mixture of polyvinyl alcohol (PVA) and glycerol were added as binders. Dispersants are useful to promote the optical properties of transparent ceramics dramatically. And binders can increase the trans-mittance in infrared range of ceramics, but it will decrease the transmittance in visible range. The 2 μm emission bands were observed under laser diode excitation at 780 nm in the doped sample with 1 at.% of Tm3+.
