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

Abstract

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) Al2O3 – (x) Sb2O3 – (0.1) Nd2O3 – (30) PbO – (59.9) SiO2 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 (Tm, μm, Eτ, Eδ & Eω) 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 (Ω2 , Ω4 and Ω6) found to be relatively better and maximum (~9.49, ~ 4.96 and ~ 4.58 × 10−20 cm2) for Al6Sb4 glass. Photoluminescence analysis, spectroscopic quality factor (~1.082), effective band width (Δλ ~ 41 nm), transition probability (At ~ 1499 s−1), stimulated emission cross section (σ ~ 1.29 × 10−20 cm2), branching ratio (β ~ 48%) and radiative life time (τrad ~ 195 μs) corresponding to the transition 4F3/2 → 4I9/2 of Nd3+ ions are suggesting Al6Sb4 glass is an useful 1.06 μm photonic resource.
