Determination of Judd–Ofelt Parameters for LiGd2-XYx:Eu3+ O3 Nanophosphor Synthesis by Combustion Method With Glycine as Fuel for Near UV Light Emitting Diode

Abstract

This paper introduces a combustion synthesis method utilizing glycine as an eco-friendly fuel for the synthesis of LiGd₂₋ₓYₓ:Eu³⁺O₃ nanophosphors. Glycine, being a naturally occurring amino acid, serves as a sustainable, renewable, and low-emission alternative to conventional fuels, minimizing the environmental impact of the synthesis process. The research focuses on analyzing Judd–Ofelt (JO) parameters to explore the luminescent properties and optical performance of the nanophosphors, with a specific emphasis on their application in near-ultraviolet (UV) light-emitting diodes (LEDs). The combustion method employed produces nanophosphors with exceptional optical characteristics while reducing both energy consumption and harmful emissions. The study includes the synthesis process, structural characterization, and photoluminescence analysis of the LiGd₂₋ₓYₓ:Eu³⁺O₃ nanophosphors. By applying JO theory, the JO parameter analysis provides valuable insights into the luminescent behavior, enabling the optimization of optical properties for improved performance in near-UV LED applications. The findings highlight the importance of JO parameter analysis in refining the luminescent efficiency of these nanophosphors. Moreover, the use of the combustion technique promotes the development of innovative materials for next-generation optoelectronic devices. This work contributes to the understanding of nanophosphor synthesis and offers potential solutions for energy-efficient, environmentally friendly lighting, addressing the increasing demand for sustainable technologies in lighting and optoelectronics.
