Y 3 Al 5 O 12 :Ce 3+ ceramics additionally doped with chromium from the gas phase were synthesized by a colloidchemical method. It was established that its luminescence spectrum included a broad poorly resolved band with a barycenter at 570 nm due to Ce 3+ and narrow bands in the region 670–750 nm due to Cr 3+ in Y 3 Al 5 O 12 and YAlO 3 . The structure of Cr 3+ optical centers in both subsystems, the kinetic properties of their luminescence, and the transfer between them of electron excitations were considered.
