Y2SiO5 doped with Ce3+ was successfully prepared at 1300 °C with the aid of Li2SO4 flux. SEM and TEM images proved that the sizes of particles making-up the powder are in the range of 1–10 μm. A small fraction of grains is nanosized. EDS spectra proved that the distribution of Y, Si and Ce is uniform. Luminescence spectra show typical broad Ce3+ luminescence in Y2SiO5 host, which peaks around 420 nm. The emission decays with the time constant of about 40 ns.
