“…The enhancement factor of ASE intensity (≈3.9 to 13.9) was also highly dependent on the spacing between the Au and perovskite, and the best thickness of buffer layer was 8 nm (Figure f). Similar effects have also been observed in the other perovskite microlasers . For example, Wang et al reported that the lasing threshold of CsPbBr 3 microrods could be reduced by 20% and the intensity was enhanced by 17.9 times when the microrods were deposited with aluminum nanoparticles (average diameter and thickness are ≈104 and ≈7.76 nm) .…”

“…The performance of photonic lasing can be improved by the SP resonance (SPR) effect generated by the metallic layer . The optical energy is greatly absorbed by the SPR, localized into nanometer scale, and gives rise to an intense electric field, which can efficiently tune the lasing properties .

progresses, grand challenges remain for semiconductor small lasers, including high power operation, expensive fabrication proceeding, and multicolor output. Exploring new optical gain materials provides a solution to overcome these problems. Recently, metal halide perovskites have attracted considerable attentions and experienced fast development in optoelectronic applications. [6][7][8][9][10] In general, perovskites are a class of compounds with general formula ABX 3 or A 2 BX 4 , where A is monovalent cation, B is divalent metal cation, and X is halide anion, respectively. Along with low-cost fabrication process, perovskites own high absorption coefficient, low trapping states, and low Auger recombination rate, which make them excellent optical gain materials for low threshold lasing devices. [11][12][13][14][15][16][17] Very recently, continuous wave (CW) optically pumped lasing has been accomplished from the structures including CH 3 NH 3 PbI 3 (MAPbI 3 ) films coupled with distributed Bragg reflector, CsPbBr 3 NWs, and so on. [18][19][20] Also, the easy tuning of optical bandgap and long carrier diffusion length promise the realization of full-visible-spectrum and electrically driven operation, respectively. [21][22][23][24][25] For pure dielectric materials, the laser size is constrained by the diffraction limit and cannot be lower than the half of optical wavelength, typically several hundred nanometers, equivalently one order of magnitude larger than the feature size of modern transistor. Surface plasmon (SP) is a collective oscillation of free electrons occurring at metal-dielectric interface. [26][27][28] After coupling with SP, the optical waves can be confined into subwavelength scale through storing their energies into the free electron oscillations. On the one hand, it leads to large enhancement of local field intensity, which has been widely used to tailor the linear and nonlinear light-matter interaction. [29][30][31][32][33][34][35][36][37][38][39] On the other hand, it provides opportunities to achieve coherent light source below the optical diffraction limitation in the form of plasmonic laser, which extensively increases the possibility of replacing electronic circuits with optical circuits in semiconductor industry. [40][41][42] Since the concept on surface plasmon amplification by stimulated emission (SPASER) was proposed in 2003, plasmonic lasers have been experimentally implemented in the structures of metallic-nanoparticle, metal-insulator-semiconductor, metallic-cladded cavities, and plasmonic lattices. [43][44][45][46][47][48][49][50][51][52][53][54] With the rapid advances in theory and materials sciences, considerable attentions have been taken onto applicable-level plasmonic lasers with high-speed, multicolor, electrically driven operation as well as their applications in Recently, low-dimensional metal halide perovskites have attracted great attention from micro/nanolaser research fields owing to their low-cost fabrication process and outstanding optical/electronic properties.

“…[ 39–41 ] The laser generation manifests itself in different ways. In most of the works, the main conclusion about the lasing nature of the emission is made based on the narrow line width and threshold behavior [ 2–5,7–16,18,19,21,22,25–27,30,32–43 ] of the emission. Rarely, the emission polarization was tested, [ 11,13,23,24,27,28,32–37,39 ] the direct observation of the light field distribution in the resonator was made, [ 10,13,14,16,18,19,21,34,39,41 ] or the laser emission directionality was observed.…”

Halide perovskites are a promising optical gain medium with high tunability and simple solution synthesis. In this study, two gain regimes, namely, amplified spontaneous emission and random lasing, are demonstrated in the same MAPbBr3 halide perovskite single crystal. For this, photoluminescence is measured at a temperature of 4 K with pulsed femtosecond pumping by UV light with an 80 MHz repetition rate. Random lasing is observed in areas of the sample where a random resonator is formed due to cracks and crystal imperfections. In more homogeneous regions of the sample, the dominant regime is amplified spontaneous emission. These two regimes are reliably distinguished by the line width, the mode structure, the growth of the intensity after the threshold, and the degree of polarization of the radiation. The spectral localization of the stimulated emission well below the bound exciton resonance raises a question concerning the origin of the emission in halide perovskite lasers.

Simultaneous Optimization of Phase and Morphology of CsPbBr₃ Films via Controllable Ostwald Ripening by Ethylene Glycol Monomethylether/Isopropanol Bi‐Solvent Engineering

et al. 2020

Both phase and morphology of perovskite films are very important for high‐performance optoelectronic devices. Although a two‐step method based on CsBr ethylene glycol monomethylether (EGME) solution can prepare pure‐phase CsPbBr3 films, they have a poor morphology due to excessive Ostwald ripening. Herein, a bi‐solvent engineering strategy is demonstrated to simultaneously optimize phase and morphology of CsPbBr3 films in a two‐step solution method, which uses the bi‐solvents of EGME and isopropanol (IPA) instead of EGME for CsBr solution at the second step. Optimizing the volume ratio of bi‐solvents and immersion time can control the Ostwald ripening effectively and result in pure‐phase, compact, and smooth CsPbBr3 films. Finally, the prepared films are applied to perovskite solar cells (PSCs) with a structure of fluorine‐doped tin oxide (FTO)/compact TiO2 (c‐TiO2)/CsPbBr3/carbon. In comparison with EGME, the champion power conversion efficiency (PCE) of devices from EGME/IPA bi‐solvents increases from 3.57% to 7.29% owing mainly to higher coverage, smoother surface, and lower trap density of CsPbBr3 films from EGME/IPA bi‐solvents. This work provides a simple and efficient method for the preparation of high‐quality CsPbBr3 films.
