文摘

Bismuth silicate (Bi₄Si₃O₁₂, BSO) thin films have been fabricated by sol-gel process. The stable sol was synthesized by using Bi(NO₃)₃¡¤5H₂O and Si(OC₂H₅)₄ (TEOS) as the precursors, acetic acid and 2-ethoxyethanol as the solvents. The thin film precursor was deposited onto SiO₂ substrates by spin-coating at 3000 rpm and was dried at 110 ¡ãC. X-ray diffraction showed that BSO phase starts to form at 700 ¡ãC and single-phase BSO polycrystalline thin films were obtained at 800 ¡ãC. The micromorphology and luminescent properties of coated films were characterized by means of scanning electron microscopy and fluorophotometer respectively.
