Distribution of luminescent centers in Ce3+-ion doped amorphous stoichiometric glass BaO–2SiO2 and dedicated glass ceramics

• Luminescent properties of Ce3+-doped stoichiometric glass BaO–2SiO2 were studied.
• Luminescent properties of the Ce3+-doped glass and the glass ceramics are similar.
• Article will be important for application of glass ceramics in luminescent devices.

We investigated the influence of crystallization conditions on the luminescent properties of Ce3+-ions doped stoichiometric glass BaO–2SiO2 at the different stages of its transformation from amorphous phase to glass ceramics. The samples were investigated by confocal luminescence spectroscopy. It was found that the luminescent properties of the cerium-doped glass and the glassceramics composite consisting of BaSi2O5 crystallites and residual glass are quite similar, though the luminescence band in the composites are slightly redshifted and narrower.
