In this study, pure and Dy³⁺ doped Ba₃(BO₃)₂ compounds were synthesized for the first time using three different synthesis methods. The synthesized compounds were characterized using various techniques, including XRD, FTIR, SEM, TEM, and DTA/TGA. Optical properties were evaluated through photoluminescence (PL) spectroscopy, X-ray luminescence, decay lifetimes, and CIE chromaticity analysis. The PL results show that Dy³⁺ doping significantly enhances the emission intensities in the blue (485 nm) and yellow (575 nm) regions, while the microwave-assisted method improves the overall crystallinity of the material. Dy³⁺ incorporation also strengthens the energy transfer mechanisms, thereby enhancing luminescence efficiency. The Dy³⁺ doped Ba₃(BO₃)₂ compound exhibits improved luminescent performance and thermal stability, indicating its strong potential as a phosphor material. The findings highlight the compound's potential applications in LED technology and pave the way for future developments in phosphor-based optoelectronic devices. This pioneering work provides novel insights into the behavior of Dy³⁺ activated Ba₃(BO₃)₂ under different synthesis conditions and establishes a solid foundation for further research and industrial application.
