Optical properties of Nd3+-doped Ca3(VO4)2 single crystal fiber

Growth, thermal and polarized spectral properties of Nd3+-doped Li3Ba2Gd3(MoO4)8 crystal

“…The effective intensity parameters, which are defined as˝e ff = (˝b +˝D 1 +˝D 2 )/3, are also listed in Table 2. The large value of˝2 mainly comes from the high absorption coefficient of the 4 I 9/2 → 4 G 5/2 + 2 G 7/2 hypersensitive transition around 585 nm [29,30]. This behavior has also been observed in some other molybdate crystals [14,15].…”

Synthesis, crystal structure and luminescent properties of pyrovanadates A2CaV2O7 (A=Rb, Cs)

“…Despite the large number of publications about luminescence properties of vanadates [1][2][3][4][5][6][7][8][9][10][11][12], the available experimental and theoretical data are not sufficient to give a unifying explanation of the nature of the luminescence centers in these compounds. There have been attempts to explain the nature of the bands in the optical spectra of vanadates by the presence of vanadium-oxygen clusters such as [VO 4 [12] (Table 4)).…”

“…Complex vanadium oxide compounds have drawn the attention of researchers and developers as promising luminescent materials [1][2][3][4][5][6][7][8][9][10][11][12]. The technical applications of vanadium oxides compounds have been proved by dozens of patents [5,6].…”

“…On the basis of complex vanadium oxides different luminescence materials have been developed and suggested, such as phosphors for plasma display panels and field-emission displays (YVO 4 :Eu) [2,3,5,6] or active laser media (YVO 4 :Ln (Ln ¼ Nd, Er, Tm, Ho)) [7][8][9][10], Ca 3 (V-O 4 ) 2 :Nd 3þ [4]. Effective and advanced crystals for diode pumped lasers can be made from YVO 4 :Nd 3þ [9,10] while luminescent screens with various luminescence spectra [3,[5][6][7][8][9][10][11][12] can be made from (Y, Gd, Lu)VO 4 , dark blue, l ¼ 470-480 nm [3], ScVO 4 , green, l ¼ 510-520 nm [3] and LuVO 4 , red , l ¼ 600-610 nm [3].…”
