Monophasic Ce~(3+) and Pr~(3+) co-doped yttrium aluminum garnet(YAG:Ce~(3+),Pr~(3+)) nanoparticles with good dispersity and uniform grain sizes in the range of 50–80 nm were prepared by a two-step route, which consisted of a modified co-precipitation preparation of mixed metal hydroxide hydrate intermediates at low temperature of about 40 oC and a subsequent calcination conversion of the synthesized intermediates to crystalline nanoparticle products at about 1000 oC. The influences of both the lanthanide ion(Ce~(3+) and Pr~(3+)) doping concentration and different doping(Ce~(3+)/Pr~(3+)) ratio on the photoluminescence intensity were systematically investigated. The synthesized (Ce_(0.6)Pr_(0.4))_(0.04)Y_(2.96)Al_5O_(12) nanoparticles were near spherical nanoclusters with good dispersity and uniform sizes in the range of 50–80 nm for about 85% of the particles. The strongest photoluminescence intensity was observed for the (Ce_(0.6)Pr_(0.4))_(0.04)Y_(2.96)Al_5O_(12) nanoparticle products.
