| Abstract: |
| The fluorochloride glasses samples with good luminescent properties in the infrared region were successfully prepared by melt quenching method. The introduction of Cl- effectively improved the mid-infrared (MIR) luminescence of erbium-doped fluoride glass at 2.7 μm nearby. According to Judd-Ofelt theory, the increase in Ω2 after the introduction of Cl- indicates an increase in the asymmetry and covalence of the sample. X-ray diffraction (XRD), absorption spectrum, Raman spectroscopy, infrared Fourier (FTIR) and infrared fluorescence spectroscopy were specifically conducted. The emission cross section (1.04×10-20 cm2) and the absorption cross section (9.68×10-21 cm2) of the sample at 2.7 μm nearby were calculated by measurement. Therefore, non-oxide erbium-doped fluorochloride glass is a good luminescent material in the MIR band. |
