In the pursuit of high-quality W-LED lighting, the precise control of emission color of phosphor materials is indispensable. Herein we report a series of single-composition Bi<sup>3+</sup>-doped LiCa<sub>3</sub>MgV<sub>3</sub>O<sub>12</sub> garnet-structure phosphors, whose emission colors under n-UV excitation could be tuned from bluish green (480 nm) to yellow (562 nm) on the basis of local lattice distortion and VO<sub>4</sub><sup>3–</sup> → Bi<sup>3+</sup> energy transfer. Furthermore, full-color luminescence tuning from bluish green to orangish red across the warm white light region was successfully achieved by designing VO<sub>4</sub><sup>3–</sup> → Bi<sup>3+</sup> → Eu<sup>3+</sup> energy transfers. More interestingly, the thermal stabilities of as-prepared samples were gradually enhanced through designing VO<sub>4</sub><sup>3–</sup>/Bi<sup>3+</sup> → Eu<sup>3+</sup> energy transfers. This work provides a new perspective for color tuning originating from simultaneous local lattice distortion and multiple energy transfers.
