Discovery of Optical Properties in 1D vdW Red Phosphorous

An international team lead by Aalto University researchers have found that when electrons are confined within the one-dimensional sub-units of fibrous red phosphorous it can show large optical responses. The photoluminescence of fibrous red phosphorous was compared to the photoluminescence of monolayer molybdenum disulfide (MoS2) which is known for its strong photoluminescence properties. It was found that the response from the fibrous red phosphorous was more than 40 times as intense albeit brief. You can find the official publication of these findings below to read further.
