Abstract

<p>Alkali halide crystals and pressed disks doped with divalent europium were prepared and their absorption and fluorescence spectra measured. There are two broad absorption bands in the ultraviolet, peaking at ~250 and 330 mµ, both due to the transition 4ƒ<sup>7</sup>→ 4ƒ<sup>6</sup>5<i>d</i><sup>1</sup>, and attributed, after comparison with the absorption spectra of Eu<sup>2+</sup> observed by previous workers in various other media, to the splitting of the 5<i>d</i> orbitals by the crystal field.</p><p>In addition to the many sharp bands riding on the main absorption bands, one peaking at 270 mµ has been observed, in complete analogy with the Gd<sup>3+</sup> spectrum. The fluorescence emission spectra are identical, irrespective of the wavelength of irradiation (250 or 330 mµ).</p>
