      abstract     = {This study explores the synthesis and luminescent
                      properties of europium-doped gallium oxide (Ga$_2$O$_3$:Eu)
                      ceramics fabricated via electron beam-assisted synthesis
                      (EBAS) at 1.4 MeV. The resulting Ga$_2$O$_3$:Eu
                      ceramicsexhibit a nanocrystalline structure with an average
                      crystallite size of ~30 nm, high crystallinity, and minimal
                      lattice strain (<0.5 \%). Luminescence analysis from 4 K to
                      300 K reveals both intrinsic and europium-induced emissions.
                      While intrinsic Ga$_2$O$_3$ emission exhibits thermal
                      quenching above 100 K, Eu$^{3+}$-related emissions, notably
                      the 611 nm red emission, show thermal stability, retaining
                      ~90 \% of their intensity at 300 K. Additionally, a novel
                      low-temperature emission peak at 1.74 eV, potentially
                      associated with electron beam-induced defects, was detected,
                      meriting further exploration. These findings indicate that
                      Ga$_2$O$_3$:Eu ceramics synthesized via EBAS hold promise
                      for optoelectronic, radiation detection, and
                      high-temperature applications, given their rapid production
                      and enhanced thermal stability.},
