Fluorescence and optical properties of Eu3+-doped borate glasses

Fabrication and optical properties of Tb3+‐doped NaCaPO4 glass‐ceramics and their radiation detection applications

“…BO 3 units and double-bonded P ═ O linkages were confirmed from the band observed at around 1324 cm −1 12,32,33. …”

“…Rare‐earth (RE)‐doped glasses are emerging as promising luminescent and dosimetric materials due to its homogeneous distinct visible emission, better thermal stability, easy preparation, inexpensive production, high transparency, and free of halo effect, and it can be used for various optical devices such as light‐emitting diodes (LED), solid‐state lasers, optical amplifiers, scintillators, and dosimeters . The OSL properties of several glasses including borate glass, silicate glass, and phosphate glass doped RE ions have already been investigated .…”

“…The OSL properties of several glasses including borate glass, silicate glass, and phosphate glass doped RE ions have already been investigated . It is well‐known that the luminescence properties of RE ions in glasses depend on the chemical composition, structure, and nature of bonds of the host glass . Na 2 O‐CaO‐P 2 O 5 ‐B 2 O 3 ‐ZrO 2 borophosphate‐based glasses systems are good hosts for RE ions because of its good optical properties, low dispersion, low refractive indices, and good transparency from the ultraviolet (UV) to the near‐infrared (IR) regions .…”

Preparation of Mn2+‐Cu+ co‐doped P2O5–ZnO–Al2O3 glasses and their red fluorescence properties

“…Most of the NH 3 and H 2 O gases generated by the reaction (2), are easily released to atmospheric air because the viscosity of the melt decreases with an increase in the melting temperature. The remaining NH 3…”

“…The Eu 3+ -, Sm 3+ -, and Mn 2+ -doped glasses have already been reported as red phosphors for color improvement of white LEDs. [3][4][5][6][7] Among them, Mn 2+ -doped phosphate glasses that show strong, broad, and red fluorescence bands due to the 4 T 1g → 6 A 1g transition of Mn 2+ ions under violet light of wavelength 410 nm, are candidates for red phosphors. 6,7 We have already reported that the P 2 O 5 -35ZnO-5Al 2 O 3 -8MnO (mole ratio) with improved water-resistance due to added Al 2 O 3 , emits the strong, broad, and red fluorescence without concentration quenching under the excitation of violet LEDs (405-415 nm).…”
