Spectroscopic properties of lead-silicate glasses with MoO3 admixture and rare earth dopants

The spectroscopic properties of lead-silicate glass containing $2 \mathrm{~mol}_{2} \mathrm{MoO}_{3}$ and rare earth dopants were investigated in detail. Three glass series were prepared, varying the concentrations of $\mathrm{Pr}, \mathrm{Nd}$, and Er from 0.5 to $1.5 \mathrm{~mol} \%$ each. The addition of MoO
3
was found to have a significant impact on the optical properties of the glass, manifesting in an elevation of the refractive index and a reduction in dispersion [1, 2]. The influence of molybdenum ions and rare earth dopants was examined through absorption, excitation, and luminescence spectra analyses [3]. Luminescence decay times were measured under both ambient conditions and within a temperature range spanning from 10 K to 350 K. Preliminary luminescence data for the glasses at room temperature are illustrated in Fig. 1.
