Shahid Iqbal

Shahid Iqbal, Physics, authored the article "Thermally controlled plasmonic modulation of HBO photoluminescence using embedded metal nanoparticles" in Chemical Physics Letters, which was accepted for publication by Elsevier B.V. In this work, we demonstrate how silver and gold nanoparticles embedded in glass via ion implantation can tune the photoluminescence of HBO fluorophores through controlled thermal processing. The study highlights the role of plasmon-fluorophore interactions in enhancing or quenching PL emission, with potential applications in optical sensing and photonic devices.
