Yttrium oxide (Y2O3) is an interesting host material for high power laser applications. Bi +3 is used in an attempt to activate Y2O3, the most promising rare-earth oxide matrix known. Bismuth doped Y2O3 samples are synthesized by simple precipitation techniques like sol-gel, solvothermal and wet chemical methods. Structural analysis is done by FTIR, XRD and SEM-EDAX and the optical properties are analysed by UV- Vis absorption studies and PL. UV- Vis absorption studies showed absorption only at 300 nm and PL shows two peaks around 420 nm and 440 nm. The emission peaks around 420nm and 440 nm for Y2O3 : Bi are due to the splitting of the excited 6s6p state into 3P0 and 3P1 states, respectively, which is originated by the spin-orbital interaction..
