Abstract:
precipitate, obtained using ammonium hydrocarbonate, contains ammonia ions as well as Y, Al, Ce. Perovskite and garnet phases form consequently in the powder under calcination; sigle garnet phase is being formed on annealing at 1100oC. Powder, obtained using ammonium hydrocarbonate as a precipitant, consists of particles smaller then 100 nm, gathered into 1-20 µm agglomerates; powder, precipitated wit ammonia water solution consists of monolithic particles with sizes of 0,5-5 µm. Both powders possess yellow photoluminescence.
