| Abstract: | Ce3+-doped lutetium oxyorthosilicate (Ce: Lu2SiO5) films have been fabricated on silicon (111) substrates by Pechini sol-gel method combined with the spin-coating technique. Thermogravimetry-differential scanning calorimetry (TG-DSC) analysis, X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), PL (Photoluminescent) measurements under VUV as well as spectroscopic ellipsometry (SE) were used to characterize the resulting films. The results indicate that the Ce: Lu2SiO5 films begin to crystallize at 900 ℃ and are completely crystallized at 1 100 ℃. The phosphor films are uniform, dense and crack-free. The VUV spectra show that the excitation is mainly host excited and the emission spectrum is a broad band centered at about 400 nm. The refractive index, the extinction of coefficient are 1.82~1.94 and 0.005~0.05, respectively, the thickness measured by spectroscopic ellipsometry is similar to that obtained by SEM. |
