Project description
Electrically pumped, amplified spontaneous emission using perovskite
Solid-state lasers rely on optically pumped solid gain media including organic materials, colloidal quantum dots and perovskites. Each of these types of media faces challenges. With the support of the Marie Skłodowska-Curie Actions programme, the PELFE project aims to overcome two current challenges with perovskite by achieving electrically pumped, amplified spontaneous emission (ASE) using perovskite. To do so, the project will conduct a comprehensive study of perovskites to better understand the correlation between compositions and ASE thresholds. The team will then maximise the optical properties of perovskite nanocrystals (PNCs) through surface etching and facet reconstruction, and then implement PNCs into LEDs.
Objective
Beyound traditional III-V laser diodes, solution-processable solid-state lasing (SPSSL) has been in spotlight due to promising versatility and simplified fabrication for integration into various platforms.
Among the classes of optical gain media, organic materials, colloidal quantum dots (CQDs), and perovskites have been extensively explored. While organic materials have shown promise, challenges remain in addressing triplet and polaron losses. CQDs, on the other hand, have demonstrated significant progress in suppressing undesirable loss mechanisms. Perovskites, a rising material, present distinct advantages including ease of formation through room-temperature processes and remarkable optical properties (low threshold of ASE and continuous wave lasing).
However, two primary challenges face perovskite implementation. Firstly, there is a notable gap in fundamental studies, specifically in understanding the correlation between auger recombination and optical properties. Secondly, the soft-ionic nature of perovskites poses a challenge for surface shell modification, necessitating the development of suitable treatment methods.
The research aims to achieve electrically pumped amplified spontaneous emission through a comprehensive study of perovskites and the introduction of a novel modification strategy. The project encompasses three objectives: understanding the correlation between compositions and ASE thresholds, maximizing the optical properties of perovskite nanocrystals (PNCs) through surface etching and facet reconstruction, and implementing PNCs into LEDs with a focus on modulating Joule heating and introducing distributed bragg reflectors.
Overall, this research endeavors achieve worlds first electrically pumped ASE using perovskite, offering a promising avenue towards efficient, cost-effective, and widely applicable laser diode technology.
