Özet

MxOy(M Co.Mn, Nd)-doped SiO2 thin films were prepared by sol-gel method on glass substrates using Si(OC2H5)(4) (tetraethylorthosilicate,TEOS,) as starting material. Si(OC2H5)(4) was dissolved in ethanol and thus, precursor solution was prepared. Various layers of coatings were obtained at room temperature by sol-gel dip-coating process at a withdrawal speed of 10 cm/min The coated substrates were exposed to heat treatment at 650 degrees C. Structural and optical properties of the films were examined by UV-VIS (Lamda 2S Spectrophotometer), AFM (Atomic Force Microscopy) and SE (Spectroscopic Ellipsometry)
