We synthetized the Eu-doped Y3Al5O12 (YAG) powder phosphors by solid state reaction under reducing atmosphere. We studied their structural, optical and paramagnetic properties by means of X-ray diffraction, time-resolved luminescence spectroscopy and electron paramagnetic resonance. Correlated measurements showed that the single Eu2+ ions are stabilized in YAG structure at yttrium position and give rise to 440 nm emission. Such a phosphor has potential for practical usage in solid state lighting..
Graphical overview of results leading to the evidence that a stable Eu2+ emission center can be stabilized in the YAG structure.
