Description
Summary:•Polarized luminescence obtained from Er3+ and Tm3+ doped glasses.•Influence of RE ions concentration and glass composition on the luminescence polarization degree.•Comparison of Er3+ and Tm3+ ions luminescence polarization degree.•The polarized luminescence properties of RE-doped glasses were explained based on the model of an optical oscillator. The partially polarized luminescence of erbium- and thulium-doped glasses exited by the linearly polarized laser radiation was observed. The dependence of the polarization degree on the RE ions concentration and on the glass matrix composition were investigated. For erbium- and thulium-doped glasses, the maximum polarization degree was shown to reach ∼0.1% and ∼1%, respectively. The polarized luminescence properties of RE-doped glasses were explained based on the model of an optical oscillator.
