EE Graduate Seminar | Hybrid perovskites: approaches towards green lasing


The high optical gain and absorption of organic-inorganic hybrid perovskites have attracted extensive research for photonic device applications. Using the bromide halide as an example, we present key approaches of our work towards realizing green lasing in hybrid perovskites. The approaches involved determination of optical constants for the hybrid perovskites thin films, understanding the material morphologies, fabrication of photonic nanostructures to reflect and manipulate light emission from the perovskite active media, and enhancing the emission property of the hybrid perovskites by using microcavity structure. Our results provide a platform for realization of hybrid perovskites based light-emitting devices for solid-state lighting and display applications.
