| Abstract | ||
| In this study, the energy gap and refractive indexes of ZnO with the change of the nanoparticle size, and put design theory for single-layer Antireflection coatings at a quarter wave thickness at λo in the UV spectrum range of 300-400 nm, when particle size is in the range of 2.4–40 nm. Aluminum oxide (Al2O3) have been selected as substrate. MATLAB language programs with version of 7.11.0 were used to describe the reflectance as a function of particle size, refractive indexes, energy gap and the wavelength at normal and oblique incidence which are depending on Brus model and Characteristic Matrix theory as a basic theory.The coating design (Air/Nano ZnO/Si) by was obtained at a lower value of (0.0278%) at the incident angle of 0° with wavelength of 350 nm and particle size of (Ps=2.8 nm). | ||
