M. F. A. Alias, Kh. M. Rashid, K. A. Adem

In this work, optical properties for thin doped ZnO films , prepared by pulse laser deposition (PLD) technique have been investigated as a function of various Ti concentrations( 0, 2, 4, 6, 8 and10) wt %. This study shows that the films have energy gap decreases from 3.3 eV to 2.4eVwith increasing Ti concentration from 0 to 10 wt%. The optical constants which are refractive index, extinction coefficient, real and imaginary constants were varied upon doping ZnO thin films with different Ti concentrations
