摘要：
We have prepared (TeO2)0.80(MoO3)0.20 glass samples containing 0.005–1.3 wt % cobalt(II) and investigated their optical transmission in the wavelength range 450–2800 nm. In this spectral region, the glasses have a strong absorption band centered at 1380 nm. From the dependence of electromagnetic radiation attenuation on cobalt concentration in the glasses, we have evaluated the specific absorption coefficient of Co2+ in the range 600–2800 nm. It has been found to be 18.4 ± 0.4 cm−1/wt % at the maximum of the 1380-nm absorption band.
