| 中文摘要 | in this work, we report a facile solution-phase synthesis of highly uniform and well-dispersed urchinlike gdpo(4) hollow spheres (around 250 nm) by utilizing the colloidal spheres of gd(oh)co(3) as a sacrificial template and nh(4)h(2)po(4) as a phosphorus source. monodisperse urchin-like gdpo(4) hollow spheres with controlled size were synthesized through the kirkendall effect via the hydrothermal process. nitrogen adsorption-desorption measurements suggest the presence of mesopores (av. 18.8 nm) in these hollow spheres. in addition, eu(3+)-doped gdpo(4) hollow spheres exhibit strong orange-red emission, corresponding to the characteristic transitions of (5)d(0) -> (7)f(1, 2, 3, 4) of eu(3+), with (5)d(0) -> (7)f(1) transition as the most prominent group. attempts were made to utilize the luminescent gdpo(4): eu(3+) hollow spheres as drug carriers. the biocompatibility test on l929 fibroblast cells using mtt assay reveals low cytotoxicity of the system. an ibuprofen-loaded gdpo(4):eu(3+) sample still shows orange-red luminescence of eu(3+) under uv irradiation, and the emission intensity of eu(3+) in the drug-carrier system varies with the released amount of ibuprofen, so that the drug together with its release situation can be easily tracked and monitored by the change in luminescence intensity. |
