选取Si-Na-Zn-Al体系作为玻璃基质,Ce ⁴⁺和Ag ⁺分别作为光敏因子和热敏因子;通过优化紫外曝光剂量与热处理条件,研究了光热敏折变玻璃中Ag ⁰团簇的析出及其对玻璃透过率、析晶等性能的影响。结果表明:通过控制紫外曝光剂量和热处理条件可以调控Ag ⁰团簇的结构和NaF晶体的析出;当紫外曝光剂量为4 J/cm ²@315 nm、成核温度为580 ℃、析晶温度为650 ℃时,可以获得均匀的Ag ⁰团簇及NaF晶体。

In this study, a Si-Na-Zn-Al system was chosen as the glass matrix and Ce 4+ and Ag + were chosen as the photosensitive and thermal factors, respectively. The precipitation of Ag 0 clusters in glass and their effects on the transmittance and crystallization of glass were studied by optimizing the ultraviolet exposure dose and heat treatment conditions. Results indicate that the structure of Ag 0 clusters and the precipitation of NaF crystals can be controlled by controlling the ultraviolet exposure dose and heat treatment conditions. Uniform Ag 0 clusters and NaF crystals can be obtained when the ultraviolet exposure dose is 4 J/cm 2 at 315 nm, the nucleation temperature is 580 ℃, and the crystallization temperature is 650 ℃.
