High lasing oscillation efficiency of Eu(III) complexes having remarkably sharp emission band
摘要:
Luminescent Eu(III) complexes with bis-phosphine oxide ligands were synthesized. Geometric structures of novel Eu(III) complexes were determined by single-crystal X-ray diffraction. One of the Eu(III) complexes showed remarkably sharp red emission and large stimulated emission cross-section (full width at half maximum (FWHM) = 2.1 nm, stimulated emission cross-section = 1.80 x 10(-20) cm(2)). The sharpness of the emission bands of the Eu(III) complexes was discussed in terms of the symmetry of the geometrical structure. (c) 2005 Elsevier B.V. All rights reserved.

In order to fabricate a high-power laser medium using Eu(III) complex, strong-luminescent Eu(III) complexes with low vibrational ligands were synthesized. One of the Eu(III) complex showed remarkably sharp red emission and large stimulated emission cross-section. The value of stimulated emission cross-section was the same order as the values of Nd-glass laser for practical use. (C) 2004 Elsevier B.V. All rights reserved.
