Broad-band and
Omnidirectional Antireflection Coatings Based on Semiconductor Nanorods
Adv. Mater. 21 (2009) 973-978
Abstract:
A broad-band and omnidirectional antireflection coating consisting of
semiconductor nanowires is fabricated. The reflection is reduced due to
a graded refractive index, which is achieved by a certain
nanorod-length distribution of cylindrical and conically shaped rods.
An increased transmission and, accordingly, a reduced reflection are
demonstrated for the visible and near-infrared parts of the spectrum.
