Plastic optical parts require antireflective as well as hard coatings. A novel design concept for coating plastics combines both functions. Symmetrical three-layer periods with a phase thickness of 3/2pi are arranged in a multilayer to achieve a step-down refractive-index profile. It is shown mathematically that the equivalent index of symmetrical periods can be lower than the lowest refractive...

Herein, eco-friendly natural acids inspired by nature, namely, acetic acid, formic lactic and citric acid on their capability of functioning as a p-dopant for the carbon nanotube transparent electrode in silicon-based planar heterojunction solar cells, are tested. From result, shows multifunctional effect p-doping with excellent doping stability well antireflection. The its investigated diverse...

Real time monitoring of contamination on antireflection (AR) silica coatings in high peak power laser systems (HPLs) is critically needed order to avoid reductions transmission and damage optical surfaces. Herein we proposed apply a surface acoustic wave (SAW) sensor real-time monitor trace amounts airborne molecular contaminants (AMCs) adsorbed the AR coatings. The coating found be susceptible...
