Abstract

In order to study new rare earth ion doped chromaticity phosphors

a color-tunable phosphor based on Dy

/Eu

co-doped ZnNb

were synthesized by a trad

itional solid-state reaction method. X-ray powder diffraction (XRD)

Scanning Electron Microscope (SEM)

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

host was proved to be a self-activated phosphor with broad absorption range from 200 to 550 nm. The color coordinate (

) values of ZnNb

: 0.08Dy

and ZnNb

: 0.08Dy

0.03Eu

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

0.33). Therefore

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

the ZnNb

: 0.08Dy

phosphors obtained may have potential application in the ultraviolet pumped white light sources and display devices etc.
