Inorganic and Hybrid Perovskite Based Laser Devices: A Review

Abstract

Inorganic and organic-inorganic (hybrid) perovskite semiconductor materials have attracted worldwide scientific attention and research effort as the new wonder semiconductor 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 direct band gap material for photovoltaic applications must be also an excellent light emitter candidate. 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, exclusively in lasing, 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.

“…Perovskite structured materials have been widely investigated for various material applications, including as fuel cells, [1][2][3][4] dielectric resonators, [5][6][7] photovoltaics, 8,9 light emitting diodes, 10 lasers, 11,12 next generation nuclear fuels 13,14 and as hightemperature superconducting magnets. [15][16][17][18] Another potential application is in the immobilisation of nuclear waste streams as a host ceramic matrix.…”

Syntheses and crystal structures of a new family of hybrid perovskites: C5H14N2·ABr3·0.5H2O (A= K, Rb, Cs)

“…'Hybrid' RMX 3 perovskites containing both inorganic and organic (molecular) components have been studied intensively in the last few years due to their remarkable photovoltaic and other optical properties (Xu et al, 2019;Stylianakis et al, 2019;Zuo et al, 2019). The R + or R 2+ organic cation replaces the metallic A cation in an oxide perovskite and the MX 3 (X = halide) octahedral network replaces the BO 3 component of an oxide perovskite.…”

Syntheses and structures of piperazin-1-ium ABr2 (A = Cs or Rb): hybrid solids containing `curtain wall' layers of face- and edge-sharing ABr6 trigonal prisms

“…. ; X = halide ion) octahedral networks have attracted intense interest because of their remarkable photophysical properties (Xu et al, 2019;Stylianakis et al, 2019;Zuo et al, 2019). A number of different organic cations occur in these hybrid structures, one of which is the doubly protonated C 4 H 12 N 2 2+ piperizinium (or piperazin-1,4-diium) ion as found in the C 4 H 12 N 2 ÁACl 3 ÁH 2 O (A = K, Rb, Cs) family (Paton & Harrison, 2010) and C 4 H 12 N 2 ÁNaI 3 (Chen et al, 2018).…”
