We present a novel strategy for the synthesis of pure and Eu-doped gamma-Ga2O3 nanoparticles with an in situ organic capping resulting from a non-aqueous solution-based benzyl alcohol synthesis route. Photoluminescence spectroscopy highlights the concomitant benzoate-related and gamma-Ga2O3 exciton-like Eu3+ excitations in the UV, and a blue emission superimposed onto gamma-Ga2O3 donor-acceptor recombination, ascribable to organic moieties different from benzoate.
