【 摘 要 】
Li and Sn codoped ZnO (LTZO) thin films have been successfully deposited on heated glass substrates at 450°C using the spray pyrolysis technique, the effect of lithium of Sn-doped zinc oxide on the structural, morphological, optical and nonlinear optical properties was investigated using X-ray diffraction, transmission, the RMS average surface roughness, and third harmonic generation (THG). The value of optical band gap Eg was found to be decreased from 3.24 eV to 3.16 eV when the concentration of Li from 0 to 7%, while the concentration of Sn is fixed at 2%.The doping of ZnO films improves the nonlinear response and the highest susceptibility value χ(3)=13.422 × 10-12(esu) is found at concentration of lithium 7%.
