Abstract: Multilayered non-quarter wavelength (design wavelength λ0 = 908 nm) based antireflection coating (ARC) has been developed by sol-gel process. Simulation of a 3-layers ARC design with the materials of refractive index ranging between 1.15 and 1.65 has been done to fulfil the experimental processing for deposition of specific thickness and refractive index. Colloidal sol based silica, polymeric sol based silica and complexed solution based zirconia were used for the fabrication of AR layers. The microstructural studies of the individual layer and also of ARC using FESEM, EDX, AFM and XRD were done separately. Surface roughnesses were found gradually decreasing by successive deposition of zirconia, colloidal silica and polymeric silica layers. Optical performance of the synthesized ARC (%0.67, at λ0) was close to that of (%0.63, at λ0) the theoretically designed value. © 2012 Springer Science+Business Media New York.
