Plasmon based antireflection coatings containing nanostructured Ag and silica medium

► The antireflection (AR) coatings of Ag nanowires and silica composite were enhanced. ► The optimal transmittance values of AR coatings with 0.10 wt.% Ag is 95.7%. ► The enhanced transmittance of the AR coatings is ascribed to plasmon effect. ► Another enhanced transmittance factor is the lesser refractive indices of coatings. ►
