First-time synthesis and investigation of structural and optical properties of Dy<SUP>3+</SUP> doped Ba₃(BO₃)₂

In this study, pure and Dy3+doped Ba3(BO3)2compounds 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)2compound 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)2under different synthesis conditions and establishes a solid foundation for further research and industrial application.
