Near-UV
single-phase white-light phosphor (Eu<sub>0.045</sub>Tb<sub>0.955</sub>CPOMBA/La<sub>0.6</sub>Eu<sub>0.1</sub>Tb<sub>0.3</sub>CPOMBA) based
on metal–organic framework was prepared by in
situ doping isostructural lanthanide MOF with Eu<sup>3+</sup> and
Tb<sup>3+</sup>, and it is found that the energy can effectively transfer
from organic ligand to lanthanides, which can overcome weak absorption
under direct excitation of lanthanide ions due to the forbidden f–f
transitions. The photoluminescence and thermostability of the new
MOF phosphor are investigated, and effective white-light emission
is achieved under 365 and 380 nm excitations. By employing Eu<sub>0.045</sub>Tb<sub>0.955</sub>CPOMBA as phosphor, we fabricated a
near-ultraviolet white-light-emitting diode (n-UV WLED) (365 nm) with
low CCT (5733 K), high CRI (<i>R</i><sub>a</sub> = 73.4),
and CIE chromaticity coordinate (0.3264, 0.3427). This approach may
open new perspectives for developing single-phase UV phosphors.
