We identify the physical mechanisms responsible for the optical homogeneous broadening in Eu^(3+):Y_2O_3 nanoparticles to determine whether rare-earth crystals can be miniaturized to volumes less than λ^3 while preserving their appeal for quantum technology hardware. By studying how the homogeneous line width depends on temperature, applied magnetic field, and measurement time scale, the dominant broadening interactions for various temperature ranges above 3 K were characterized. Below 3 K the homogeneous line width is dominated by an interaction not observed in bulk crystal studies. These measurements demonstrate that broadening due to size-dependent phonon int...
