Abstract

PbO-ZnO-P₂O₅ glass doped with 0.6, 0.8 and 1.0 % Er³⁺ was irradiated with 1.5 MeV Ar⁶⁺ beam of fluence

5 \times 10^{15} / c m^{2}

. Change in optical band gap shows a small reduction of 0.2 % at 0.6 % doping in irradiated sample. Refractive index decreases due to irradiation by 0.001–0.002 which turns out to be lower than other classes of glass. The change of Judd-Ofelt (JO) parameter

Ω_{2}

reveals stabilization of divalent Er²⁺ states at 1 % doping and reduced inversion symmetry around Er³⁺at 0.6 % doping due to irradiation. Parameter

Ω_{4}

indicates change in rigidity and viscosity in irradiated sample. Calculated lifetime of some excited states using JO parameters shows enhanced possibility of 1.5 µm LASER emission upon irradiation at 1 % doping. Change in structural, bonding units is captured via Raman data. Our study proposes that JO analysis could be a new route to study the effect of heavy ion irradiation on lanthanide doped glass.

期刊介绍： The Journal of Non-Crystalline Solids publishes review articles, research papers, and Letters to the Editor on amorphous and glassy materials, including inorganic, organic, polymeric, hybrid and metallic systems. Papers on partially glassy materials, such as glass-ceramics and glass-matrix composites, and papers involving the liquid state are also included in so far as the properties of the liquid are relevant for the formation of the solid. In all cases the papers must demonstrate both novelty and importance to the field, by way of significant advances in understanding or application of non-crystalline solids; in the case of Letters, a compelling case must also be made for expedited handling.
