SeO₂ based glass system of the composition 39 PbO–(60-x) B₂O₃– xSeO₂:1.0 Yb₂O₃ (with 10 ≤ x ≤ 50) were synthesized. Analysis of the results of structural studies revealed that the glass network consists of [SeO₄]²⁻ and [SeO₃]²⁻ units; the studies further indicated an increasing fraction of [SeO₃]²⁻ units and decreasing concentration of [SeO₄]²⁻ groups with increase of SeO₂ content. Optical Absorption (OA) and photoluminescence (PL) spectra have displayed bands due to ²F_7/2 → ²F_5/2 and ²F_5/2 → ²F_7/2 transitions, respectively. Evaluated absorption and emission cross-sections and lifetime of the excited state of Yb³⁺ ions exhibited increase with SeO₂ content. Results of PL studies indicated nearly fourfold increase of PL output with increase of SeO₂ content up to 50%. Such increase is attributed to the increased concentration of isolated [SeO₃]^2- pyramidal groups. Overall, the rise of SeO₂ content in PbO–B₂O₃–SeO₂ glass system facilitated the increase of PL emission of Yb³⁺ ions largely.
