dc.description.abstractA new class of rare-earth doped borate phosphors, Ba2Cd(BO3)(2): xEu(3+) (x = 2, 3, 4, 5, and 6 mol%), was synthesized using the high-temperature solid-state reaction technique in air. X-ray diffraction (XRD) confirmed the phase formation of Ba2Cd(BO3)(2), while Fourier transform infrared spectroscopy (FT-IR) revealed the presence of trigonal [BO3] units. The surface morphology was studied using field emission scanning electron microscopy (FE-SEM), and energy dispersive spectroscopy (EDS) identified the elements. Photoluminescence (PL) analysis showed that the phosphors emitted at 592, 613, 652, and 701 nm, corresponding to the D-5(0) -> F-7(1), D-5(0) -> F-7(2), D-5(0) -> F-7(3), and D-5(0) -> F-7(4) transition of Eu3+ ions, respectively. The 613 nm red emission, from the D-5(0) -> F-7(2) transition, was strongest for the 6 mol% Eu3+ sample. The emission intensity increased with Eu3+ concentration, peaking at 6 mol%. CIE chromaticity, correlated color temperature (CCT), and color purity calculations showed acceptable color coordinates (0.6426 and 0.3548), a low CCT value (2355 K), and high purity (91.34%), making the 6 mol% Eu3+-doped phosphor ideal for red light in white light-emitting diodes (WLEDs).
