| 中文摘要 | y2o3: eu3+ phosphor layers were deposited on monodisperse sio2 particles with different sizes ( 300, 500, 900, and 1200 nm) via a sol-gel process, resulting in the formation of y2o3: eu3+@sio2 core-shell particles. x-ray diffraction ( xrd), fourier transform infrared spectroscopy (ft-ir), field emission scanning electron microscopy (fe-sem), transmission electron microscopy ( tem), time-resolved photoluminescence ( pl) spectra, and lifetimes were employed to characterize the y2o3: eu3+@sio2 core-shell samples. the results of xrd indicated that the y2o3: eu3+ layers began to crystallize on the silica surfaces at 600 degrees c and the crystallinity increased with the elevation of annealing temperature until 900 degrees c. the obtained core-shell particles have perfect spherical shape with narrow size distribution and non-agglomeration. the thickness of the shells could be easily controlled by changing the number of deposition cycles ( 60 nm for three deposition cycles). under the excitation of ultraviolet ( 250 nm), the eu3+ ion mainly shows its characteristic red ( 611 nm, d-5(0)-f-7(2)) emissions in the core-shell particles from y2o3: eu3+ shells. |
