Eu2+ stabilization in YAG structure: optical and electron paramagnetic resonance study
Original language description
A set of Eu-doped YAG phosphors was successfully synthesized by solid-state reaction under the Ar:5%H2 atmosphere. Their physical properties were investigated by means of XRD, time-resolved luminescence spectroscopy, and EPR. Special attention was given to well-grounded confirmation of Eu2+ occurrence in the YAG structure. The influence of Eu concentration, form of doping (EuS, EuF2, or Eu2O3) and number/form of annealing steps was studied. Corresponding characteristics were measured and evaluated in a broad temperature range. The correlated measurements showed that the single Eu2+ ions stabilized in YAG in the yttrium position are responsible for the 440 nm emission. The corresponding lowest energy excitation band is situated at 300 nm, and the radiative lifetime of Eu2+ emission is about 500 ns. A phenomenological model of excited state dynamics was used to explain the experimentally observed features. Possible practical exploitation of the Eu2+ center in the YAG host is discussed.
