| 中文摘要 | y0.9eu0.1bo3 phosphor layers were deposited on monodisperse sio2 particles of different sizes (300, 570, 900, and 1200 nm) via a sol-gel process, resulting in the formation of core-shell-structured sio2@y0.9eu0.1bo3 particles. x-ray diffraction (xrd), field emission scanning electron microscopy (fe-sem), transmission electron microscopy (tem), photoluminescence (pl), and cathodoluminescence (cl) spectra as well as lifetimes were employed to characterize the resulting composite particles. the results of xrd, fe-sem, and tem indicate that the 800 degrees c annealed sample consists of crystalline ybo3 shells and amorphous sio2 cores, in spherical shape with a narrow size distribution. under uv (240 nm) and vuv (172 nm) light or electron beam (1-6 kv) excitation, these particles show the characteristic d-5(0)-f-7(1-4) orange-red emission lines of eu3+ with a quantum yield ranging from 36% (one-layer y0.9eu0.1bo3 on sio2) to 54% (four-layer y0.9eu0.1bo3 on sio2). |
