“…Furthermore, lathanide activated luminescent glasses have some assorted advantages over the conventional phosphors employed in the white light emitting diodes such as better heat resistance, less power consumption, superior luminous properties and their ease of production. Luminescent glasses have emerged as an appropriate alternative for white light emitting diodes because of exhibiting non-halo effect and resin free assembly which can control the loss of scattering light produced at the phosphor-resin interface due to the large difference in refractive index [6,7]. The pristine glass matrix is an important aspect for manufacturing lanthanide doped photonic devices.…”

A series of singly and doubly Ce3+ / Eu3+ doped lithium borate (LBZ) glasses have been synthesized via melt quenching. XRD and SEM analysis confirmed the non-crystalline nature of glasses. The emission spectrum of Ce3+: LBZ glass reveals an extensive blue emission band at 447 nm (5d→4f) by exciting with 350 nm. An intense excitation band noticed at 393 nm (7F0→5L6) of Eu3+ in Eu3+: LBZ glass, which is associated with the excitation wavelength of near-ultraviolet LED chip. The luminescence spectra of Eu3+ disclose a strong red emission at 612 nm (5D0→7F2) excited with 393 nm. By raising the content of Eu3+ ions, the luminescence features were embellished remarkably. However, the dazzling red emission intensity of Eu3+ was ameliorated by the insertion of Ce3+ ions in co-activated glass due to energy transmission. Spectral overlap, fluorescence studies, decay dynamics, CIE coordinates and color purity corroborated the transfer of energy from Ce3+ to Eu3+. The CIE color coordinates of the optimized (1.0 Ce3+ + 1.0 Eu3+) co-doped glass has been shifted to the white light region. In view of these spectral features, 1.0 mol % Ce3+ + 1.0 mol % Eu3+: LBZ glass could be suggested as a promising candidate for the white light applications.
