Abstract
Monophasic Ce3+ and Pr3+ co-doped yttrium aluminum garnet (YAG:Ce3+,Pr3+) 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 °C and a subsequent calcination conversion of the synthesized intermediates to crystalline nanoparticle products at about 1000 °C. The influences of both the lanthanide ion (Ce3+ and Pr3+) doping concentration and different doping (Ce3+/Pr3+) ratio on the photoluminescence intensity were systematically investigated. The synthesized (Ce0.6Pr0.4)0.04Y2.96Al5O12 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 (Ce0.6Pr0.4)0.04Y2.96Al5O12 nanoparticle products.
