Abstract

doped and co-doped Gd

(WO

)

nanocrystalline powders were prepared by chemical co-precipitation method

respectively. The structure and luminescent properties of nanocrystalline Gd

(WO

)

∶Eu

and Gd

(WO

)

∶Eu

were studied by using XRD and fluorescence spectrophotometer. The results show that the crystal phase of the samples as prepared is base centered monoclinic structure. When the mole fraction of Eu

is 20%

the luminescent intensity of Eu

is the greatest. Sm

sensitized Eu

in the samples Gd

(WO

)

∶Eu

. The sensitized effect of Sm

on Eu

was more obvious when the sample Gd

(WO

)

∶Eu

was excited by 464 nm light than by 395 nm light. Sm

can realize the energy transfer from Sm

to Eu

making the emission of

more strength. When the mole fraction of Sm

was 5%

the luminescent intensity of the sample Gd

(WO

)

∶20%Eu

5%Sm

was the greatest. The transition of

was clearly observed under 405 nm or 440 nm excitation. Therefore

and Sm

co-doped in the matrix Gd

(WO

)

greatly expanded the range of the wavelength of the excitation light source.
