Development and Characterization of Novel Phosphor Solutions for Enhanced White LED Technology
Main Article Content
Abstract
The advancement of white light-emitting diodes (LEDs) has significantly transformed lighting technology due to their high efficiency, long lifespan, and eco-friendliness. Central to the performance of white LEDs is the development of phosphor materials that convert blue or near-UV LED emissions into broad-spectrum white light. This study focuses on the development and detailed characterization of novel phosphor solutions tailored for enhanced white LED applications. We synthesized innovative phosphor materials using controlled chemical methods, optimizing their luminescent properties to achieve higher quantum efficiency and improved color rendering index (CRI). Comprehensive analyses, including photoluminescence spectroscopy, thermal stability testing, and morphological studies, were performed to assess the performance and reliability of these phosphors under operating conditions. The results demonstrated that the newly developed phosphors exhibit superior luminescent intensity, better thermal quenching resistance, and improved stability compared to conventional materials. Additionally, integration of these phosphors in prototype LED devices showcased enhanced luminous efficacy and more natural white light output. This work provides valuable insights into the material design strategies required to meet the growing demands of white LED technology for diverse applications such as general lighting, displays, and automotive lighting. The findings underline the potential of these novel phosphor solutions to contribute significantly to the future of energy-efficient and high-quality white LEDs.
