| Abstract: | Dimethyl sulfoxide complex of europium nitrate was synthesized. Its composition is Eu(NO3/)3·4(CH3)2SO. The crystal structure of this complex belongs to monoclinic system. Its lattice parameters are:α= 1.4806 nm, b= 1.0948nm, с= 1.5335nm. β= 108.07o and Z= 4. Space group is C2/c-C2k6. Coordination number of Eu3+ is 10. Its luminescence spectra weredetermined at liquid nitrogen temperature (Fig. 3). Argon laser was used for excitation. The excitation wavelength is 457.9nm. |
