- Abstract
Gold nanoparticles (Au NPs) doped monolithic and transparent sodium borosilicate glass has been synthesized by both sol-gel and atmosphere control heat treatment methods. Fourier transform infrared (FTIR) spectra in the wavenumber range of 400 to 4000 cm were applied to collect variation information of surface groups of the samples in the sintering process. The microstructure of Au NPs in the glass was characterized by means of X-ray powder diffraction (XRD), transmission electron microscopy (TEM), and high-resolution TEM (HRTEM). Meanwhile, the linear optical properties of the glass were analyzed by UV-vis spectrometer between the wavelength of 300 and 1000 nm, and a broad absorption band around 600 nm was observed. The third-order nonlinear optical properties of the glass were investigated by using Z-scan technique at the wavelength of 800 nm, pulse duration of 190 fs, and repetition rate of 20 Hz. The glass showed saturable absorption and self-focusing nonlinear refraction, and the optical nonlinear susceptibility χ was estimated to be 1.7 × 10 esu, with the single-pulse energy of 1 μJ.
