	{We report the design and fabrication of Bi3+ and Eu3+ co-doped Ca2Ga2GeO7 (CGGO) phosphors for highperformance warm-white light-emitting diodes (LEDs). The phosphor exhibits efficient Bi3+ -\&gt; Eu3+ energy transfer, as evidenced by spectral overlap, enhanced Eu3+ emission, and quenching of Bi3+ emission with increasing Eu3+ content. The emission color shifts from blue to red with increasing Eu3+, achieving near-white emission at 3\% Eu3+ (x = 0.33</p>
