Significant Variations in the Luminescence of Samarium(II) Doped Strontium and Barium Octaborate as a Function of Excitation Wavelength and Sample Temperature.

The emission features characteristic of divalent samarium formed in samarium-doped barium octaborate (BaBO) and strontium borate (SrBO) have been studied as a function of excitation wavelength and sample temperature. The emission spectra of divalent samarium in both materials exhibit a surprisingly strong temperature dependence. When divalent samarium is doped into BaBO, changes in excitation wavelength and sample temperature both result in significant variations in the emission features associated with the material.
