Abstract

and Eu

co-doped Lu

phosphors were synthesized by the high temperature solid-state reaction. The structure of the sample was characterized by XRD

the morphology was observed with scanning electron microscope

the excitation spectra and emission spectra were measured

and the effects of Li

and Eu

doping

concentration and the calcined temperature on the luminescence intensity of the synthesized samples were analyzed. The results show that the emission of the sample with 2.5%Li

1%Na

and 5%Eu

co-doped Lu

is the strongest in the four samples calcined at 800 ℃ in the air for 2 h. In the same condition

the luminous intensity of Lu

:5%Eu

2.5%Li

1%Na

is 1.89 times than that only with 2.5%Na

doping

3.97 times than that only with 2.5%Li

doping

and 6.43 times than that without Li

and Na

doping.
