Abstract Dy 3+ and Tb ions doped Ba 2 Cd(BO 3 ) phosphors with varying concentrations (2, 3, 4, 5, 6 mol%) were produced via the solid-state synthesis method in air. The as-synthesized characterized. photoluminescence (PL) excitation (PLE) spectra of 2, mol% reveal four distinct emission bands blue, yellow, red regions, 575 nm band ( 4 F 9/2 → H 13/2 , electric dipole transition) exhibiting a notably higher intensity than 481 15/2 magnetic transition). optimal doping concentration was identified as 5 mol%, beyond which quenching effects became apparent. Additionally, demonstrate efficient energy absorption at approximately 225 nm, characteristic observed 415, 436, 488, 544, 586, 621 corresponding to D 7 transitions, respectively. ideal for (5 (6 are x = 0.3717, y 0.4064, 0.2902, 0.5344, respectively, per Commission Internationale de l’Eclairage (CIE) color spectrum, positioning -doped within yellow spectrum green spectrum. These exhibit vibrant luminescence, demonstrating their suitability candidates applications these hues. They can be employed when stimulated by near-UV, UV, blue laser diodes WLEDs.
