Nd2O3 Influenced Al2O3 & Sb2O3 Functional PbO-SiO2 Glass Materials, 1.06 μm Photonic Resource.

• Thermal stability, elastic evaluations advised the glasses prepared were flexible and hard. • Trap depth parameters (T m , μ m , E τ , E δ & E ω) advised that the glass Al 6 Sb 4 is a useful TL resource. • Glass Al 6 Sb 4 found to be best in JO Parameters (Ω 2 , Ω 4 and Ω 6) is a useful optical resource. • Radiative parameters (Δλ, A t , σ, β & τ rad) directing that the glass Al 6 Sb 4 is a useful PL asset. Silicates of neodymium oxide are well known for laser diode (or) white light emitting diode applications. However, there is a lot of need and necessity of high efficient laser (or) light emitting diodes. In such a way, the materials (10 – x) Al 2 O 3 – (x) Sb 2 O 3 – (0.1) Nd 2 O 3 – (30) PbO – (59.9) SiO 2 were synthesized, where the variable 'x' varies as 0, 2, 4, 6, 8 & 10 mol%. Dimensionally, arranged samples studied by structural, physical, elastic, thermoluminescent and optical characterization techniques. Analysis with regard to structure of present materials reveal that the glasses prepared were mechanical hard. Trap-depth parameters (T m , μ m , E τ , E δ & E ω) with regard to thermoluminiscence studies suggest, glasses prepared were thermally active for visible light. Judd – Ofelt theory well applied for optical studies. J-O Parameters (Ω 2 , Ω 4 and Ω 6) found to be relatively better and maximum (~9.49, ~ 4.96 and ~ 4.58 × 10−20 cm2) for Al 6 Sb 4 glass. Photoluminescence analysis, spectroscopic quality factor (~1.082), effective band width (Δλ ~ 41 nm), transition probability (A t ~ 1499 s−1), stimulated emission cross section (σ ~ 1.29 × 10−20 cm2), branching ratio (β ~ 48%) and radiative life time (τ rad ~ 195 μs) corresponding to the transition 4F 3/2 → 4I 9/2 of Nd3+ ions are suggesting Al 6 Sb 4 glass is an useful 1.06 μm photonic resource.
