摘要：

Coatings of SiO2CeO2 have been prepared on microscope slides using the dip coating technique to obtain films with a high UV absorption. Different compositions have been prepared by varying the ratios of SiO2/TiO2 and TiO2/CeO2. The optical behaviour of these films have been followed by spectrophotometric measurements. Absorption spectra of the coatings show that a TiCe equimolar complex is responsible for an absorption band centered at 290 nm, due to Ce3+ ions. Thick films (0.5-1 μm) of intense yellow colour with high reflectance and high UV absorption have been obtained which may find interesting applications. © 1990.
