Abstract

:Eu

nano-powders were prepared by co-precipitation and solvo-thermal methods

respectively. The microstructural evolution of Lu

:Eu

phosphor powders obtained by above two methods were analyzed and compared by means of XRD

FTIR and SEM. The obtained powders without any additive were sintered into transparent ceramics under vacuum at 1 100 ℃ for 5 h and then in nitrogen atmosphere at 1 700 ℃ for 2 h and at 1 600 ℃ for 10 h. The excitation and emission spectra of Lu

:Eu

for the calcined powders and transparent ceramics were respectively measured at room temperature. Transparencies of the obtained transparent ceramics were compared. The fluorescence decay was measured and discussed under different excitation wavelengths for the prepared Lu

:Eu

transparent ceramics.
