White light-emitting diode (LED) technology has witnessed rapid advancements driven by the demand for energy-efficient and environmentally friendly lighting solutions. Central to these developments is the role of phosphor materials, which convert the LED’s primary emission into broad-spectrum white light. This review comprehensively summarizes recent progress in the synthesis, characterization, and application of novel phosphor solutions for white LED technology. Various classes of phosphors, including rare-earth-doped oxides, nitrides, and sulfides, as well as emerging nanostructured and quantum dot-based materials, are discussed in terms of their optical properties, thermal stability, and compatibility with LED devices. The review highlights strategies to overcome common challenges such as thermal quenching, color rendering limitations, and efficiency droop. Furthermore, it explores innovative approaches to tailor emission spectra for improved luminous efficacy and color quality, essential for diverse applications ranging from general lighting to displays and automotive illumination. The integration of phosphors in different LED architectures and their impact on device performance are also critically examined. By providing a thorough understanding of current trends and future prospects, this review aims to guide researchers and industry professionals in the development of next-generation phosphor materials that can meet the evolving requirements of white LED technology. The synthesis techniques, characterization methods, and application potentials discussed herein are crucial for advancing efficient, durable, and high-quality white lighting solutions.
