| 中文摘要 | highly uniform alpha-nayf4:yb/er hollow microspheres have been successfully prepared via a simple two-step route. first, the core-shell structured mf@y(oh)co3:yb/er precursor was fabricated by a urea-based homogeneous precipitation method using colloidal melamine formaldehyde (mf) microspheres as template. then the y(oh)co3:yb/er precursor was transformed into hollow nayf4:yb/er (alpha and beta mixed phase) by a subsequent solvothermal method, and mf microspheres were dissolved in the solvent simultaneously. the mixed phase of nayf4:yb/er was transferred into pure alpha-nayf4:yb/er by calcination. the as-prepared hollow microspheres were well characterized by x-ray diffraction (xrd), scanning electron microscopy (sem), transmission electron microscopy (tem), energy-dispersive x-ray spectrum (eds), fourier transform infrared spectroscopy (ft-ir), thermogravimetric analysis (tga), and upconversion (uc) luminescence spectroscopy. it is found that the template can be removed without additional calcination or etching process. alpha-nayf4:yb/er hollow microspheres exhibit bright upconversion (uc) luminescence under 980 nm laser diode (ld) excitation. furthermore, the hollow microspheres show sustained and ph-dependent doxorubicin hydrochloride (d ox) release properties; in particular, the emission intensity increases with the release amount of drug, making the release process able to be tracked or monitored by the change of the emission intensity, which demonstrates the high potential of this kind of hollow fluorescent material in drug delivery fields. |
