Abstract

Absorption and emission spectra of Sm³⁺ and Eu³⁺ co-doped lithium borate glass of the following composition: xSm₂O₃ + (100 - x)[0.84H₃BO₃ + 0.15Li₂O + 0.01Eu₂O₃], where x = 0.0, 0.1, 0.2, 0.5, 0.6 and 0.7 mol%, have been reported. The concentration of Sm³⁺ was varied keeping the Eu³⁺ concentration fixed at 0.01 mol%. Optical absorption and emission spectra have been measured in the spectral range from 350 to 2400 nm. The oscillator strength, Judd-Ofelt intensity parameters, branching ratios and radiative transition probabilities were calculated. The obtained results are discussed and compared with other literature data for Eu³⁺ in various compounds.
