Abstract

We have recorded part of the UV-visible region of the electronic spectrum of EuOCl at both 292 and 77 K by diffuse reflectance spectroscopy. Illumination of the sample and collection of the reflected light was accomplished through the use of an all-quartz fiberoptic probe. Several absorption maxima were observed which result from transitions from the ⁷F₀ ground state and ⁷F₁ excited state to the ⁵D₄ ⁵G_2,4,6 ⁵L₆, and ⁵D₃ excited states of the Eu³⁺ ion.
