G. Chadeyron et al., INFLUENCE OF THE SYNTHESIS METHOD ON THE LUMINESCENT PROPERTIES OF THE VATERITE-TYPE YBO3-EU3+, Comptes rendus de l'Academie des sciences. Serie II. Mecanique, physique, chimie, astronomie, 320(4), 1995, pp. 199-203
The vaterite-type YBO3 yttrium orthoborate is prepared by solid state
chemistry as well as the sol-gel method. The fluorescence of the Eu3ion is investigated in the Y1-xEuxBO3 compounds for 0 < x < 0.30 at 30
0 and 77 K upon excitation at 337.1 nm. The influence of the synthesis
method is painted out. The spectroscopic data are consistent with two
kinds of site for Eu3+.
