A class of ultrasmall fluorescent core-shell silica nanoparticles developed at Cornell is showing an unexpected ability to ...

According to the Optical Society of America, U.S. researchers have been able to create a practical optical fiber with a silicon core. As they were able to use the same commercial methods that are used ...

The maximum absorption wavelength of silicon solar cells (SSCs) is approximately 1100 nm, due to the inherent bandgap limitations of silicon materials. This constraint results in significant optical ...
