dc.description.abstract | CaF2:Eu3+ glass-ceramic sol-gel materials have been examined for reddish-orange
photoluminescence applications. The transformation from precursor xerogels to glass-ceramic materials
with dispersed fluoride nanocrystals was verified using several experimental methods: di erential
scanning calorimetry (DSC), thermogravimetric analysis (TG), X-ray di raction (XRD), transmission
electron microscopy (TEM), infrared spectroscopy (IR-ATR), energy dispersive X-ray spectroscopy
(EDS) and photoluminescence measurements. Based on luminescence spectra and their decays,
the optical behavior of Eu3+ ions in fabricated glass-ceramics were characterized and compared to
those of precursor xerogels. In particular, the determined luminescence lifetime of the 5D0 excited
state of Eu3+ ions in nanocrystalline CaF2:Eu3+ glass-ceramic materials is significantly prolonged
in comparison with prepared xerogels. The integrated intensities of emission bands associated
to the 5D0 ! 7F2 electric-dipole transition (ED) and the 5D0 !7F1 magnetic-dipole transition
(MD) are changed drastically during controlled ceramization process of xerogels. This implies the
e cient migration of Eu3+ ions from amorphous silicate sol-gel network into low-phonon energy
CaF2 nanocrystals. | pl_PL |
