| 1 | Magnetic and thermosensitive luminescent nanocomposites based on Fe_3O_4/SiO_2/poly(N-isopropylacrylamide)/lanthanidepolyoxometalates and their controllable luminescence properties显示文摘Magnetic and temperature-responsive luminescent composites based on poly(N-isopropylacrylamide),magnetic nanoparticles and Na_9[EuW_(10)O_(36)] were fabricated. The composites were investigated by IR, UV,XRD, TGA, SEM and TEM. The prepared nanocomposites exhibit good superparamagnetic property and thermo-responsive switchable luminescence properties. The multifunctional nanocomposites can be separated by external magnetic field. Moreover, the nanocomposites exhibit an appreciable temperature response, and the red luminescence of the nanocomposites in solution can be controlled by the temperature stimuli. The hydrogel emits strong redluminescence in solution at 25 ℃,which can be seen by naked eyes. When the external temperature is 40 ℃, the red luminescence almost disappears in solution.It is expected that the multifunctional nanoparticles have potential applications in the field of biomedicine. | Jun Wang Si Chen Hao Liu Wuke Li | 2018 | Journal of Rare Earths2018，36，7： | 2 |
