Controlling and Optimizing Amplified Spontaneous Emission in Perovskites.
ACS Appl Mater Interfaces

Article Synopsis
- Perovskites are gaining significant attention as materials for tunable lasers, with recent studies focusing on their amplified spontaneous emission (ASE) when optically pumped, particularly noting their low thresholds.
- Research highlights that vacuum deposition of CsPbBr perovskites offers better ASE performance than solution-processed versions, achieving a threshold of 35 μJ/cm by identifying optical loss as a key factor.
- A model linking ASE characteristics with gain length, optical loss, and other parameters is presented, demonstrating successful ASE in perovskite samples with metal electrodes, indicating potential for electrically pumped laser designs.
