Abstract
Indium-silver alloy quantum dots doped sodium borosilicate(NBS) glass was prepared by Sol-Gel method with controlled atmosphere technology. The morphology and microstructure of AgIn alloy quantum dots in the glass were characterized by means of X-ray powder diffraction(XRD), X-ray photoelectron spectroscope(XPS), high- resolution transmission electron microscope(HRTEM) and electron diffraction(SAED). The fluorescent properties of the glass by fluorescence spectrometer were studied. The results showed that indium-silver alloy quantum dots with an average grain size of 5 nm were finely dispersed in the sodium borosilicate glass after heat-treated at 600℃. Indiumsilver alloy quantum dots in the glass exhibited a fluorescence peak at around 435 nm which nominated AgIn quantum dots doped NBS glass as the candidate glass for laser sources, nonlinear media and photonic applications.
