Cr-doped Y_3Sc_xAl_((5-X)_O_(12)(Nd:YSAG) powder have been prepared with a combustion method. The powders are nanosized and a pure cubic phase when calcined at 900℃. Transparent Cr:YSAG ceramics were successfully fabricated by sintering the powder compact at 1800℃ under H2 atmosphere. The optical properties were investigated in detail. It was found that after Sc substitute for Al, the The octahedral crystal-field parameter Dq and Dq/B was reduced, and that is why the absorption peak move to the longer wavelength side but the emission peak not moved.
