一种低温制备SiO_(2)/Ag薄膜及其防蓝光性能研究

Preparation of a SiO_2/Ag Thin Film and Its Blue Light Filtering Properties

显示和人工照明的普及使生活环境富蓝光化。蓝光在全彩显示和白光照明中具有重要作用,但长时间暴露会危害视觉安全。由于防蓝光薄膜制备温度较高,因此,本文基于SiO_(2)和Ag纳米粒子,开发一种低温防蓝光薄膜作为低温制备材料。该薄膜可过滤短波蓝光,并保持500nm以上可见光的高透过率。实验表明:n(Si)∶n(Ag)比例为1∶0.05的薄膜在(415~455)nm范围内,短波蓝光截止率为53.32%;在(500~800)nm范围内,可见光透过率为95.08%;在降低蓝光危害25.8%情况下,色坐标仅偏移5%。

The popularity of display and artificial lighting has enriched the living environment with blue light.Blue light plays an important role in full-color display and white lighting, but long-term exposure can harm visual safety.Due to the high preparation temperature of anti-blue light film, this paper developed a low-temperature anti-blue light film based on SiO_(2) and Ag nanoparticles as a low-temperature preparation material.The film filters short-wave blue light and maintains a high transmittance of visible light above 500nm.The results show that the short-wave blue cut-off rate is 53.32% for the films with the ratio of n(Si)∶n(Ag) 1∶0.05 in the range of(415~455)nm;In the range of(500~800)nm, the visible light transmittance is 95.08%.Under the condition of 25.8% reduction of blue light damage, the color coordinate shift is only 5%.
