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 Bi3+-doped LiCa3MgV3O12 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
VO43– → Bi3+ energy
transfer. Furthermore, full-color luminescence tuning from bluish
green to orangish red across the warm white light region was successfully
achieved by designing VO43– →
Bi3+ → Eu3+ energy transfers. More interestingly,
the thermal stabilities of as-prepared samples were gradually enhanced
through designing VO43–/Bi3+ → Eu3+ energy transfers. This work provides a
new perspective for color tuning originating from simultaneous local
lattice distortion and multiple energy transfers.
