| 中文摘要 | up-conversion (uc) luminescent porous silica fibers decorated with nayf(4):yb(3+), er(3+) nanocrystals (ncs) (denoted as nayf(4):yb(3+), er(3+)@silica fiber) are prepared by the electrospinning process using cationic surfactant p123 as a template. monodisperse and hydrophobic oleic acid capped beta-nayf(4): yb(3+), er(3+) ncs are prepared by thermal decomposition methodology. then, these ncs are transferred into aqueous solution by employing cetyltrimethylammonium bromide (ctab) as secondary surfactant. the water-dispersible beta-nayf(4):yb(3+), er(3+) ncs are dispersed into precursor electrospinning solution containing p123 and tetraethyl orthosilicate (teos), followed by preparation of precursor fibers via electrospinning. finally, porous alpha-nayf(4):yb(3+), er(3+)@silica fiber nanocomposites are obtained after annealing the precursor fibers containing beta-nayf(4):yb(3+), er(3+) at 550 degrees c. the as-prepared alpha-nayf(4):yb(3+), er(3+)@silica fiber possesses porous structure and uc luminescence properties simultaneously. furthermore, the obtained nanocomposites can be used as a drug delivery host carrier and drug storage/release properties are investigated, using ibuprofen (ibu) as a model drug. the results indicate that the ibu-loaded alpha-nayf(4):yb(3+), er(3+)@silica fiber nanocomposites show uc emission of er(3+) under 980 nm nir laser excitation and a controlled release property for ibu. meanwhile, the uc emission intensity of ibu-alpha-nayf(4):yb(3+), er(3+)@silica fiber system varies with the released amount of ibu. |
