中文摘要nano-submicrostructured cawo4, cawo4 : pb2+ and cawo4 : tb3+ particles were prepared by polyol method and characterized by x-ray diffraction (xrd), field emission scanning electron microscopy (fe-sem), transmission electron microscopy (tem), fourier transform infrared spectra (ft-ir), thermogravimetry-differential thermal analysis (tg-dta), photoluminescence (pl), cathodo-luminescence (cl) spectra and pl lifetimes. the results of xrd indicate that the as-prepared samples are well crystallized with the scheelite structure of cawo4. the fe-sem images illustrate that cawo4 and cawo4 : pb2+ and cawo4 : tb3+ powders are composed of spherical particles with sizes around 260, 290, and 190 nm respectively, which are the aggregates of smaller nanoparticles around 10-20 nm. under the uv light or electron beam excitation, the cawo4 powders exhibits a blue emission band with a maximum at about 440 nm. when the cawo4 particles are doped with pb2+, the intensity of luminescence is enhanced to some extent and the luminescence band maximum is red shifted to 460 nm. tb3+-doped cawo4 particles show the characteristic emission of tb3+ d-5(4)-f-7(j) (j=6-3) transitions due to an energy transfer from wo42- groups to tb3+.
