ZrO

especially in nano scale

with interesting properties in mechanics

thermal

has been widely used in ceramic

high-temperature solid cell

. With the development of methods for mesoporous materials

mesostructured zirconia has attracted great interest in catalysis

self-organized materials and biomedicine. In this paper

luminescence properties of highly ordered porous ZrO

synthesized by surfactant-assisted route and post-synthetic treatment of surface modification

were studied and the emission intensity of ZrO

can be improved after the modification. An aqueous solution of analytically pure ZrSO

TMABr solution under certain temperature and molar ratio during continuous stirring. After stirred for 3h

the mixtures were loaded in PTFE-lined stainless steel autoclaves and heated from 90℃ to 120℃ for 24h. The precipitated products were filtered

washed and dried at 100℃. The dried precipitate was afterwards treated with phosphoric acid solution and then calcined in flowing air at 500℃ for 6h to remove the surfactant. And to modify the surface

some sample were successively dipped into the solution of Zn(Ac)

has highly ordered hexagonal pores of about 1.8nm and has strong blue and ultraviolet light emission whose intensity is 100 times higher than that of the bulk samples.Therefore

the luminescence intensity of suface-modified sample is 3 times higher. Under the excitation by 240

the emission with the same spectral structure of four emission peaks at 380

so one can conclude these peaks are related to the same emission center

while the emission ( λ
