ABSTRACT Lu 3 MgAl 3 SiO 12 :Ce 3+ (LuMASG:Ce 3+ ) transparent ceramics (TCs) represent a promising material for LED lighting applications. To meet the diverse demands for light sources across various applications, a series of Gd 3+ ‐doped LuGdMASG:Ce 3+ and Tb 3+ ‐doped LuMASG:Ce 3+ , Tb 3+ TCs with varying doping concentrations were prepared. The obtained TCs exhibited high transmittances of 81.5% and 70.3% at 600 nm, respectively. In addition, Gd 3+ doping effectively induced a redshift of the emission spectrum to 598 nm, while the incorporation of Tb 3+ compensated for the deficiency in the green spectral region. Consequently, the color rendering index (CRI) was enhanced to 80.7 and 77.6, respectively. This strategic ion‐doping approach provides an effective pathway for the development of high‐performance LED lighting and wide color gamut displays.
