Abstract

|
Fluorescence spectra and life time of Eu3+ ion in borosilicate glass medium are measured. Electronic transitions of Eu3+ ion in borosilicate glass medium are found to come from 5D0→7FJ(J=0, 1, 2, 3, 4) transitions of SL coupling system in f6 electrons configuration. From the number of Stark sublevels in spetra, crystal field for Eu3+ ion is also found to have the symmetric character of low symmetry order, n≤2. The fraction and the number of components of life times were varied depending on the composition of Eu3+ in borosilicate glasses, from which the binding condition between the Eu3+ ion and anionic oxygen of borosilicate glass can be deduced.
