The total amount of data generated worldwide is expected to reach 175 zettabytes (1 ZB equals 1 billion terabytes) by 2025. If 175 ZB were stored on Blu-ray disks, the stack would be 23 times the ...

These sensors are made of lanthanide-doped upconversion optical materials, which helps the researchers convert low-energy near-infrared photons into high-energy short-wave visible photons.

NUS chemists have developed a new class of crystalline materials to potentially harvest near-infrared (NIR) radiation. Nonlinear optical process (NLO) describes the nonlinear behaviour of light as it ...

(Nanowerk News) Solar cell technologies have been improving incrementally over the decades, but energy conversion has remained less than optimal. Now, researchers at Kyoto University have developed a ...

Photon upconversion involves a series of non-linear optical processes where the sequential absorption of two or more photons leads to the emission of a single photon with energy greater than the sum ...

Upconversion nanoparticles are a new generation of fluorophore, relying on both physical and chemical principles to convert photons from a lower energy state to a higher energy state. It is common for ...

A significant advance in 'optical tweezer' technology will help boost biomedical research. Much like the Jedis in Star Wars use 'the force' to control objects from a distance, scientists can use light ...
