Ever-increasing demand for information density and accuracy in highly integrated photonic devices present greater technical requirements for the new generation laser materials. Low-dimensional hybrid perovskites have attracted great attention as a new type of laser medium. Especially, the outstanding stability, excellent optical gain and flexible wavelength tunability predict the quasi-two-dimensional perovskites as candidate to achieve stable high-quality perovskite lasers strategically. In this project, combined with the structural and crystal engineering, we carried out controllable growth and laser properties investigations of multiple quantum well compositional distribution in the quasi-two-dimensional perovskite. Quantified the composition structure of multiple quantum wells, then summarize the internal regulation mechanisms for the multiple quantum well components modulation. Investigated the photophysical processes and carrier dynamics in quasi-two-dimensional perovskite systems, we try to clarify the structure-effect dependence of laser properties of the multiple quantum wells distribution in quasi-two-dimensional perovskite. This project would promote high-efficient perovskite laser investigations, providing a new approach for realizing laser display and photonics applications theoretically.
