Spectroscopic properties of nonlinear NdSc3(BO3)4

Abstract

NdSc 3 (BO 3 ) 4 ͑NdSB͒ can be grown as a nonlinear optical crystal having hexagonal ͑huntite͒ structure. The crystal has important spectroscopic properties suitable for various applications in photonics. The observed crystal-field splitting of the energy levels of Nd 3ϩ (4 f 3 ) has been identified based on analyses of the fluorescence, absorption, and excitation spectra obtained at 13, 80, and 300 K. A detailed crystal-field splitting calculation in which initial crystal-field parameters B nm are established from lattice-sum calculations gives good agreement to the observed splitting. Experimental branching ratios and fluorescence lifetimes are reported and are compared with calculated values. The spectroscopic properties of Nd 3ϩ in NdSB are also compared with values obtained for Nd 3ϩ as a dopant in the nonlinear crystal YAl 3 (BO 3 ) 4 .

Improved lasing property of neodymium-doped lanthanum scandium borate microchip laser

“…The Stark level of 4 F 3/2 at room temperature was depopulated with low temperature of 6K. We could observe the expected number of transitions (J+1/2) from 4 F 3/2 to the six Stark levels of 4 I 11/2 as in NdSc 3 (BO 3 ) 4 6 . The 6K emission spectrum consists of six peaks.…”

“…However, Nd:LSB has some complicated crystal phases. At least four space groups of Nd:LSB, C2/c (α-phase), R32 (β-phase), Cc (γ-phase), and C2, have been reported [5][6] with their own optical properties. Nd:LSB is polymorphous compound, and has hexagonal (huntite) crystal structure.…”

Spectroscopic properties of Nd0.5Gd0.5Fe3(BO3)4 single crystal

“…Special interest is connected with Nd 3+ ions in borate matrices with huntite structure. Borates RM 3 (BO 3 ) 4 (R-Y or rare earth (RE) metal, M-Al, Ga, Cr, Fe, Sc) are trigonal crystals with huntite-like structure (space group R32 (D 7 3 )) without center of inversion. Therefore, crystals of this type can be used as selfdoubling laser media.…”

“…Therefore, crystals of this type can be used as selfdoubling laser media. In particular, optical, luminescent, nonlinear and laser properties of neodymium containing alumoborates were studied in a number of works (e.g., [5][6][7][8][9][10][11][12]). To the best of our knowledge, there were no similar works concerning ferroborates.…”

Crystal and band structure of K2AlTi(PO4)3 with the langbeinite-type structure

“…With the development of technology and science, there is an increasing need for new multifunctional magnetic materials, ultraviolet (UV) phosphors, scintillators, and laser materials, which have extensive applications in several domains [1][2][3][4][5][6][7][8][9]. Coordination networks based on [M 2 (PO 4 ) 3 ] fragment may result in diverse structure types with consequent interesting magnetism, electricity, optic and thermal expansion properties.…”
