Abstract
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.
Highlights
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 glass was cutted into plates with thickness of 1 mm, that were annealed on air at 850◦C for 30 min and 900◦C for 15 min
The shape of the luminescence band and the center of the mass of the luminescence band to detect the possible formation of new bands or the transformations of the luminescence band were studied
Summary
There is a strong demand for development of new inorganic luminescent materials which nowadays shows tremendous progress through nanoengenering of the materials. Most of the silicate crystalline materials while doped with Ce, possess blue luminescence band at near UV excitation, what is a bottleneck that hinders their application for lighting. Glass ceramic materials possess several advantages combining the properties of crystals and glass, especially the high thermal conductivity. Recent study of europium doped barium disilicate glass system showed that luminescent properties of the material are strongly affected by crystallization [4, 5]. To study the sensitivity of the resulting luminescence spectrum to the ratio between the crystallized and residual amorphous parts of the glass, we investigated the luminescence properties of cerium doped glass BaO–2SiO2 and glass ceramics obtained from this glass at different temperature and duration of thermal treatment
