Inorganic and Hybrid Perovskite Based Laser Devices : A Review

Abstract

Inorganic and organic – inorganic (hybrid) perovskite semiconductor materials have attracted the worldwide scientific attention and research effort as the new wonder material in optoelectronics. Their excellent physical and electronic properties have been exploited to boost the solar cells efficiency beyond 23% and captivate their potential as competitors to the dominant silicon solar cells technology. However, the fundamental principles in Physics dictate that an excellent material for photovoltaic applications must be also an excellent light emitter. This has been realized for the case of perovskite based light emitting diodes (LEDs) but much less for the case of the respective laser devices. Here, the strides have been made since 2014 are presented for the first time. The solution processability, low temperature crystallization, formation of nearly defect free, nanostructures, the long range ambipolar transport, the direct energy band gap, the high spectral emission tunability over the entire visible spectrum and the almost 100% external luminescence efficiency show perovskite semiconductors’ potential to transform the nanophotonics sector. The operational principles, the various adopted material and laser configurations along the future challenges are reviewed and presented in this paper.

Synthesis conditions influencing formation of MAPbBr3 perovskite nanoparticles prepared by the ligand-assisted precipitation method

“…Nanostructured lead halide perovskite materials have gained significant attention in the last few years mainly because of their potential for application in the field of electronics and photonics. There are several available reports demonstrating their implementation into light emitting diodes (LED) 1 – 3 , solid-state lasers 4 , solar cells 5 , photodetectors 6 and optical cooling systems 7 . Especially the photoluminescence quantum yields (PLQY) of up to 100% make these nanostructured perovskite materials very interesting 8 .…”

Recent Advancement on the Excitonic and Biexcitonic Properties of Low-Dimensional Semiconductors

“…Some works examined new different excitonic properties of the 2D organicinorganic halide perovskite materials showing that this type of perovskite is very qualified to be used for the construction of the photonics devices [96][97][98] containing LEDs [99,100], photodetectors [101], transistors, and lasing applications [102]. Wang et al [103] provided a valuable research about the special characteristics of the long-lived exciton, trion, and biexciton cases in CdSe/CdTe colloidal QWs, proposing a novel model of light harvester with minimal energy losses.…”

Perovskite Nanoparticles

“…PNSs represent larger exciton binding energies and longer carrier decay times than those of bulk crystals. In addition to this, their narrow emission band makes them good candidates for LED [16] and laser [17]. Since Schmidt et al reported the synthesis of first colloidal PNS by a simple procedure under ambient conditions in 2014 [18], many research groups have started working on these materials.…”
