Аннотация: New noncentrosymmetric rare earth borate Rb3NdB6O12 is found in the ternary system Rb2O-Nd2O3-B2O3. The Rb3NdB6O12 powder was fabricated by solid state synthesis at 1050K for 72h and the crystal structure was obtained by the Rietveld method. Rb3NdB6O12 crystallized in space group R32 with unit cell parameters a =13.5236(4), c =31.1Показать полностью62(1)A, Z =3. From DSC measurements, the reversible phase transition (I type) in Rb3NdB6O12 is observed at 852-936K. The 200?m thick tablet is transparent over the spectral range of 0.3-6.5?m and the band gap is found as E g ?6.29eV. Nonlinear optical response of Rb3NdB6O12 tested via SHG is estimated to be higher than that of K3YB6O12. Blue shift of Nd luminescent lines is found in comparison with other borates. The vibrational parameters of Rb3NdB6O12 are evaluated by experimental methods. © 2017 Society of Powder Technology Japan.
