Researchers used theoretical calculations assessing electron orbital symmetry to synthesize new molecule designed to be both transparent and colorless while absorbing near-infrared light. This ...

Researchers at the Indian Institute of Science (IISc) have fabricated a device to increase or "up-convert" the frequency of short infrared light to the visible range. Up-conversion of light has ...

The human eye can only see light at certain frequencies (called the visible spectrum), the lowest of which constitutes red light. Infrared light, which we can’t see, has an even lower frequency than ...
