Anti-reflection (AR) coating is an excellent spectacle lens option for increasing luminous transmission of the lens, reducing glare, and enhancing the cosmetic appearance of the wearer [4]. It is recommended for virtually all types of eyewear, including clear lenses for general, everyday use as well as nighttime driving; photochromic lenses for patients who frequently move between indoors and o...

Terahertz technology [1], at present a dynamically developing field, was enabled by advances in ultra-short pulse lasers and semiconductor coherent sources in the frequency range of 1–50 THz. The extensive activities are focused on THz optics, spectrally bright sources, and detectors. The terahertz time-domain spectroscopy and terahertz imaging are main fields, where terahertz technology finds ...

Anti-reflective coatings (ARCs) are used to lower the reflection of light on the surface of a substrate. Here, we demonstrate that the two main drawbacks of moth eye-structured ARCs-i.e., the lack of suitable coating materials and a process for large area, high volume applications-can be largely eliminated, paving the way for cost-efficient and large-scale production of durable moth eye-structu...

When the sunlight illuminates the front surface of solar cell, part of the incident energy reflects from the surface, and part of incident energy transmits to the inside of solar cell and converts into electrical energy. Typically, the reflectivity of bare silicon surface is quite higher; more than 30% of incident sunlight can be reflected. In order to reduce the reflection loss on the surface ...

We have employed attenuated total reflection Fourier transforms infrared spectroscopy sATR-FTIRSd to monitor the profile evolution of patterned mesoporous, low-dielectric-constant SiO2 films in situ and in real time during plasma etching. A stack of patterned photoresist, anti-reflective coating, and mesoporous SiO2 is etched in an inductively coupled plasma reactor, using CHF3 and Ar. During e...
