Cerium‐doped yttrium aluminum garnet can be used in white light emitting diodes and lasers. The YAG powders are traditionally formed by the solid state method, but the product particles are large, irregular, and non‐homogeneous, which is detrimental for its luminescence properties. We present here a simple and fast method for synthesizing YAG:Ce 3+ nanopowder based on solution combustion synthesis from metal nitrates (Ce content between 0.7 and 35 wt%) and fuel (urea, starch, or glucose) water mixtures. The calcination of the raw product at 900 °C for 2 h yielded crystalline garnet nanopowder with grain size well below 100 nm. The properties of the final product were characterized by XRD, SEM, ATR, TG/DTA, and spectrofluorimetric measurements.
