Perovskite Lasing

Caption

A layer of perovskite is shown lasing green under continuous operation at room temperature. Research from Kyushu University and Changchun Institute of Applied Chemistry, Chinese Academy of Sciences, indicates that suppressing triplet excitons is important for overcoming the lasing death phenomenon that has so far prevented long operation from the low-cost materials.
