Perovskites Nanostructures: A Promising Material for Lasing

Perovskite materials have emerged as a promising candidate for application in solar energy harvesting. However, after the successful synthesis of highly emissive nanostructures made from all-inorganic Cesium-Lead-Halide perovskites, this class of materials became of interest to lighting applications. 

In a recent paper by Nagamine, published in The Journal of Physical Chemistry Letters, we have shown that amplified spontaneous emission can be obtained at very low pump intensities in CsPbBr3 quantum dots, even for multi-photon excitation. This behavior is favored by the strong Coulomb interaction of multi-excitons in this material.
