Ionic cerium-doped pure silica glass with high photoluminescence, has been prepared using the sol–gel technique and densification of the porous xerogel under inert and air atmosphere.The present study shows the effect of densification atmosphere and molar concentrations on the optical properties of ionic cerium-activated silica glasses.Moreover, the PL intensity increased with increasing the molar concentration of ionic Ce+3.The PL is composed of two sub-bandsascribable to tetragonal distortion of the matrix and spin–orbit coupling but these sub-bands arecloser to each other when the core rod is densified under inert atmosphere.
