Blending organic electron donors and acceptors yields intermolecular charge-transfer states with additional optical transitions below their optical gaps. In organic photovoltaic devices, such states ...
A new study presents a method to record the temperature of materials with exceptional temporal resolution, using a Doppler broadening effect in neutron resonance absorption. Using a high-powered laser ...
