中文摘要well-dispersed, uniform y2o3:ln(3+) (ln(3+) = eu3+, tb3+) hollow microspheres have been successfully prepared via a urea-assisted homogeneous precipitation method using polystyrene (ps) as templates, followed by a subsequent calcination process. x-ray diffraction (xrd), scanning electron microscopy (sem), transmission electron microscopy (tem), fourier transform infrared (ft-ir), thermogravimetric analysis (tga), photoluminescence (pl) spectra, and cathodoluminescence (cl) spectra were employed to characterize the samples. the results demonstrate that the samples can be well indexed to the pure cubic phase of y2o3. the tem and sem images indicate that the shell of the uniform hollow spheres, whose diameter is about 2.1 mu m, is composed of many uniform nanoparticles with diameters of around 20 nm. upon ultraviolet (uv) and low-voltage electron beam excitation, the y2o3:ln(3+) (ln(3+) = eu3+, tb3+) samples exhibit bright red (eu3+, d-5(0) -> f-7(2)), and green (tb3+, d-5(4) -> f-7(5)) luminescence. this material may find potential applications in light display systems, optoelectronic devices and drug delivery based on the uniform hollow structure, dimensions, and luminescence properties. furthermore, this synthesis route may be of great significance in the preparation of other hollow spherical materials.
