Wurtzite ZnO possesses a wide band gap of 3.37 eV and a large exciton binding energy of 60 meV at room temperature. ZnO has been extensively studied because of its potential applications in various fields, such as gas sensor, solar cells, photodetectors, light emitting diodes and laser systems. Rare earth doped ZnO has attracted much attention as a luminescent material for both fundamental research and applications. Cerium and europium doped ZnO thin films were grown by Pulsed Laser Deposition (Nd:YAG, λ= 266 nm, τ = 6 ns) from Ce2O3:ZnO (1% Ce) and Eu2O3:ZnO targets, respectively, in oxygen or nitrogen ambient. ZnO films were deposited on fused silica and Si (100) substrates at substrate temperature of 300°C and at room temperature. Optical properties were analyzed by optical spectroscopy, spectrophotometric measurement and spectral ellipsometry. Structural properties were characterized by XRD.
