Abstract

The article delves into the optical and luminescent characteristics of ZnO and TiO2 nanopowders synthesized through an optimized pulsed laser reactive ablation method. It highlights the significant role of crystal lattice defects in forming luminescence centers and influencing energy transfer processes. The study also explores how laser annealing modifies these properties, offering valuable insights into enhancing the selectivity of gas-sensitive materials and gas sensors. Through comprehensive analyses, including Raman scattering and photoluminescence spectroscopy, the research uncovers the structural quality and defect evolution of the nanopowders, providing a detailed understanding of their luminescent behavior.
