(Color online) Absorption spectra of thin films.
Cross-sectional SEM image of an undoped ZnO thin film on glass substrate.
(Color online) XRD patterns of thin films annealed at in air.
(Color online) Normalized transmittance of the films as a function of input fluence. The circles are experimental data, while solid curves are theoretical fits. For excitation, data are fitted for a two-photon process using Eq. (1). For excitation, data are fitted for a three-photon process using Eq. (2).
Lattice parameters, band gap energy, and nonlinear optical coefficients obtained for the thin films.
