photoluminescence spectra and decay curves were utilized to characterize the as-prepared phosphors. The ZnNb

phosphors were already very close to the standard white light (0.33

Dy

was selected as the sensitizer ion and red component from Eu

adjusted to control the emission color. The energy transfer from Dy

to Eu

was confirmed based on the luminescence spectra and decay curves. Furthermore
the energy transfer mechanism was deduced to be the dipole-quadrupole interaction. In general
