Effect of Rotation Rate on Iron Oxide Thin Films Prepared by Spin Coating

Abstract

Iron oxide thin films had been deposited on glass substrate by spin coating. Spectrum of x-ray diffraction for films of Fe2O3 prepared by concentration (0.3M) has been studied. Also the spectrum shows that the films are polycrystalline structure in the wurtzite phase and by orientation (104) at angle (2θ=33.1023°) .The AFM measurements show that the increase in rotation velocity decreasing the grain size. From optical properties, the transparency of films reach 65-90 % for different velocities. The absorption coefficient and urbach energy decrease with increase velocity, while the energy gap decrease with velocity.
