Luminescent properties and energy transfer of Ce3+-activated Li2O–B2O3–Gd2O3 scintillating glasses under VUV–UV and X-ray excitation

Fascinating functional properties of Mn:Gd2O3 nanocrystalline phosphor

“…Further, blue-shifted band (390-402) nm is appeared due to Mn doping. The emission of Gd 3+ ion at UV region of electromagnetic spectrum peaked around (266-271) nm was the most intensive band and assigned due to a transition from 6 P 7/2 to 8 S 7/2 corresponding to internal f-f transitions of Gd 3+ ion [30,31]. The broad peak near 266 nm may be due to the oxygen to Mn charge transfer band (CTB).…”

Self‐reduction of Eu3+ to Eu2+ in europium‐doped Li2B4O7 glass prepared in air

“…Especially, the Li 2 B 4 O 7 glass incorporated with rare earth or transition metals shows excellent optical properties for high thermomechanical stability and a wide spectral range of transparency from deep UV to IR regions . The optical properties of dysprosium and cerium‐doped lithium borate glasses for the purpose of LEDs and scintillation application, and the strategy on enhancing the emission intensity of Ce 3+ ions by adding reduction agents, such as carbon and Si 3 N 4 , were studied in our work . However, as one of the most promising scintillating activators in glasses and ceramics, divalent europium has been rarely proposed .…”

“…27 The optical properties of dysprosium and cerium-doped lithium borate glasses for the purpose of LEDs and scintillation application, and the strategy on enhancing the emission intensity of Ce 3+ ions by adding reduction agents, such as carbon and Si 3 N 4 , were studied in our work. [28][29][30] However, as one of the most promising scintillating activators in glasses and ceramics, divalent europium has been rarely proposed. [11][12][13] Herein, for the first time, the self-reduction of Eu 3+ to Eu 2+ ions in europium-doped Li 2 B 4 O 7 glass induced by partially replacing B 2 O 3 with BN was reported in the present work, and the optical properties including transmittance, photoluminescence and radioluminiescence spectra, together with the luminescence decay curves are systematically revealed.…”

Thermal, structural, optical, and photon shielding studies of cerium‐doped barium tellurite glasses

“…Cerium exhibits remarkable properties such as polyvalent states of Ce 4+ + e − → Ce 3+ , electronic transitions between interbond (4f↔5d), and high strength optical absorption in the UV region. [ 6–11 ]…”
