Abstract:
In this work, we present the results of the structure and luminescence properties of YAG:Ce
(Y3Al5O12 doped with Ce3+ ions) ceramic samples. Their synthesis was carried out by sintering
samples from the initial oxide powders under the powerful action of a high-energy electron beam
with an energy of 1.4 MeV and a power density of 22–25 kW/cm2
. The measured diffraction patterns
of the synthesized ceramics are in good agreement with the standard for YAG. Luminescence characteristics at stationary/time-resolved regimes were studied. It is shown that under the influence of
a high-power electron beam on a mixture of powders, it is possible to synthesize YAG:Ce luminescent ceramics with characteristics close to the well-known YAG:Ce phosphor ceramics obtained by
traditional methods of solid-state synthesis. Thus, it has been demonstrated that the technology of
radiation synthesis of luminescent ceramics is very promising.
