Optical and FTIR spectra of NdF3-doped borophosphate glasses and effect of gamma irradiation

FTIR spectra and properties of iron borophosphate glasses containing simulated nuclear wastes

“…The absorption bands at ～1360 cm -1 and ～1441 cm -1 are due to the symmetric stretching vibrations of P=O bonds [30,39] and vibration modes of [BO 3 ] and BO 2 O - [31], respectively. The other bands observed at the wavenumbers higher than 1500 cm -1 are related to the vibrations of H-O-H, POH, and BOH [31,33,34].…”

Effect of doping of Nd3+ ions in BaO–TeO2–B2O3 glasses: A vibrational and optical study

“…These transitions were assigned by comparing the band positions in the transmission spectra with a standard wavelength chart for Nd 3+ ion. The various spectroscopic transitions observed for Nd 2 O 3 containing glasses are as follows: 2 P 1/2 (429 nm), 4 G 11/2 + 2 K 15/2 (460 nm), 2 G 9/2 (473nm), 4 G 9/2 (512nm), 4 G 7/2 (525 nm), 4 G 5/2 + 2 G 7/2 (582 nm), 4 S 3/2 + 4 F 7/2 (747 nm), 4 F 5/2 + 2 H 9/2 (799 nm), 4 F 3/2 (863 nm) [46]. These transitions correspond to transitions from the ground state to various excited states of 4f N configuration.…”

Concentration dependence of spectroscopic properties and energy transfer analysis in Nd 3+ doped bismuth silicate glasses

“…2 presents the absorption spectra in the range of 400e1000 nm in Nd 3þ doped bismuth silicate glasses. Eight absorption bands are observed, which are assigned to the transitions of 4 I 9/2 / 4 G 9/2 , 4 G 7/2 , ( 4 G 5/2 , 2 G 7/2 ), 2 H 11/2 , 4 F 9/2 , ( 4 F 7/2 , 4 S 3/2 ), ( 4 F 5/2 , 2 H 9/2 ) and 4 F 3/2 at 514, 527, 585, 624, 684, 749, 806, 879 nm, respectively [17]. It can be seen that each absorption band becomes stronger with the increment of Nd 2 O 3 concentration.…”
