Perovskite random lasers: a tunable coherent light source for emerging applications

Abstract

Metal halide perovskites have attracted increasing attention due to their superior optical and electrical characteristics, flexible tunability, and easy fabrication processes. Apart from their unprecedented successes in photovoltaic devices, lasing action is the latest exploitation of the optoelectronic performance of perovskites. Among the substantial body of research on the configuration design and light emission quality of perovskite lasers, the random laser is a very interesting stimulated emission phenomenon with unique optical characteristics. In this review article, we first comprehensively overview the development of perovskite-based optoelectronic devices and then focus our discussion on random lasing performance. After an introduction to the historical development of versatile random lasers and perovskite random lasers, we summarize several synthesis methods and discuss their material configurations and stability in synthesized perovskite materials. Following this, a theoretical approach is provided to explain the random lasing mechanism in metal halide perovskites. Finally, we propose future applications of perovskite random lasers, presenting conclusions as well as future challenges, such as quality stability and toxicity reduction, of perovskite materials with regard to practical applications in this promising field.

Synthesis and Characterization of Silver-Gold Bimetallic Nanoparticles for Random Lasing

“…Studies of sensors and light sources based on random lasers are developing very fast. Recent research includes the usage of silver nanoparticles and polymer film on fiber facet [36], whispering-gallery mode lasers [37], fabricating random laser-based humidity sensor by using polymer membrane doped with silver nanoparticles [38] and tunable coherent light source based on metal halide perovskites [39]. Thus, we believe that this research is useful for studies of sensing and light sources due to its simple experimental set up, structure and flexible design.…”

Optoelectronic devices based on the integration of halide perovskites with silicon-based materials

“…18 Up to date, most of perovskite lasers are optically pumped. Nanostructures in optically pumped laser could not only provide optical feedback, 149,150 but also reduce the lasing threshold as well as increase the quality factor by reducing the roughness and providing better light connement. 23 Perovskite nanostructures, such as single crystalline nanowires and nanoplates, can be used as both gain media and optical microcavities, which is particularly promising for high-quality small-sized laser sources.…”
