Abstract

(

=Eu

or Tb

) single-doped -SrHPO

phosphors with nano-scale grain were synthesized by the hydrothermal method in this work. The morphological and optical properties of these phosphors were also investigated. The sizes of the -SrHPO

nanorods are found in the range of 90 to 200 nm in length and 24 to 36 nm in width. The introduction of doping agent ions of Eu

or Tb

decreases both the quality of the crystallinity and the aspect ratio of the matrix. Under the excitation of near ultraviolet light (395 nm)

-Sr

0.97

HPO

:0.03Eu

exhibits two main emission peaks at 590 nm and 614 nm

corresponding to the

(

2) transition of Eu

respectively. Under the excitation of near ultraviolet light (217 nm)

-Sr

HPO

:0.03Tb

shows only one predominant emission peak at 543 nm originated from the

transition of Tb

. The CIE chromaticity coordinates for -Sr

:0.03Tb

phosphor observed in the yellowish green region.
