| 中文摘要 | rare-earth (eu3+, tb3+)-doped ca2y8(sio4)(6)o-2 luminescent thin films were dip-coated on silicon and quartz glass substrates through a sol-gel route. x-ray diffraction (xrd), scanning electron microscopy (sem) and luminescence excitation and emission spectra as well as luminescence decays were used to characterize the resultant films. the results of xrd reveal that these films remain amorphous below 700 degreesc, begin to crystallize at 800 degreesc, and crystallize completely around 1000 degreesc with an oxyapatite structure. the grain structure of the film can be seen clearly from sem micrographs, where particles with various shape and average size of 250 nm can be resolved. the eu3+ and tb3+ ions show their characteristic red (d-5(0)-f-7(2)) and green (d-5(4)-f-7(5)) emission in the films with a quenching concentration of 10 and 6 mol% (of y3+), respectively. the lifetime of eu-3divided by increases with the heat treatment temperature front 700 to 1100 degreesc. |
