Abstract

Neutron diffraction structure study has been performed on YAl 3(BO 3) 4 (YAB), on doped Y 0.88Er 0.12Al 3 (BO 3) 4, Y 0.5Er 0.5Al 3 (BO 3) 4, Y 0.5Yb 0.5Al 3 (BO 3) 4 and on co-doped Y 0.84Er 0.01Yb 0.15Al 3 (BO 3) 4 compositions. It was established that the doped compounds are isostructural to YAB. The neutron diffraction pattern have been be fitted in space group R32 using the triple hexagonal Wyckoff notation. Both Er 3+ and Yb 3+ ions occupy the Y 3+ (3a) sites and not the Al 3+ (9d) sites, as it was suggested previously. The lattice parameters are decreasing with increasing amount of the dopant elements. Slight changes are revealed in the positional parameters and interatomic distances with increasing concentration of the dopant ions. For the co-doped Y 0.84Er 0.01Yb 0.15Al 3(BO 3) 4 the changes are more significant than for the doped YAB compounds with only one type of dopant element, Er or Yb.
