| 中文摘要 | well-shaped y2o3:eu hollow microspheres have been successfully prepared on a large scale via a urea-based homogeneous precipitation technique in the presence of colloidal carbon spheres as hard templates followed by a subsequent heat treatment process. xrd results demonstrate that all the diffraction peaks of the samples can be well indexed to the pure cubic phase of y2o3. tem and sem images indicate that the shell of the uniform hollow spheres, whose diameters are about 250 nm, is composed of many uniform nanoparticles with diameters of about 20 nm, basically consistent with the estimation of xrd results. furthermore, the main process in this method was carried out in aqueous condition, without the use of organic solvents or etching agents. the as-prepared hollow y2o3:eu microspheres show a strong red emission corresponding to the d-5(0)-f-7(2) transition of the eu3+ ions under ultraviolet or low voltage excitation, which might find potential applications in fields such as light phosphor powders, advanced flat panel displays, field emission display devices, and biological labeling. |
