AbstractDy3+-doped yttrium aluminum garnet (YAG) nanocrystalline powders were synthesized by employing a sol-gel combustion process, in which triammonium citrate was used as both fuel reagent and dispersant. The influence of citrate-to-nitrate molar ratio (0-2) on slurry rheology, phase formation, composition, morphology, and particle size distribution of the Dy:YAG powders was evaluated systematically. The effects of Dy3+ dopant concentration (various from 1 to 3 at.%) and annealing temperature (1000-1300 A degrees C) on the structural and optical properties of Dy:YAG phosphors were also investigated, and the chromaticity coordinates of the phosphor were calculated. Results show that pure Dy:YAG nanopowders were produced by calcining the combustion synthesis products with a citrate-nitrate ratio of 1 at or above 850 A degrees C. Study of the luminescence behavior of the synthesized powders reveals that the phosphors exhibit greenish-blue emission pre-annealing and red emission post-annealing. Furthermore, emission band intensity is increased with an increase in both the Dy3+ dopant concentration and annealing temperature. The Dy:YAG phosphor's temperature-dependent variation between greenish-blue and red luminescence emission makes it attractive as a potential candidate for applications in temperature monitoring of fuel sprays.
