Low-temperature solution-processed wavelength-tunable perovskites for lasing.
Low-temperature solution-processed materials that show optical gain and can be embedded into a wide range of cavity resonators are attractive for the realization of on-chip coherent light sources. Organic semiconductors and colloidal quantum dots are considered the main candidates for this application. However, stumbling blocks in organic lasing include intrinsic losses from bimolecular annihil...
متن کاملControllable lasing performance in solution-processed organic-inorganic hybrid perovskites.
Solution-processed organic-inorganic perovskites are fascinating due to their remarkable photo-conversion efficiency and great potential in the cost-effective, versatile and large-scale manufacturing of optoelectronic devices. In this paper, we demonstrate that the perovskite nanocrystal sizes can be simply controlled by manipulating the precursor solution concentrations in a two-step sequentia...

2. Materials, fabrication, and characterization To overcome the insolubility problem of the inorganic precursor salts of rare-earth dopant ions in the polymer host, the Nd 3+ ions were encapsulated in a stable organic complex, Nd(TTA)3phen (TTA = thenoyltrifluoroacetone, phen = 1,10-phenanthroline) (Fig. 1a). The Nd-complex was dissolved into the polymer waveguide material, a solution of 6-FDA/...
متن کاملLow-threshold amplified spontaneous emission and lasing from colloidal nanocrystals of caesium lead halide perovskites
Metal halide semiconductors with perovskite crystal structures have recently emerged as highly promising optoelectronic materials. Despite the recent surge of reports on microcrystalline, thin-film and bulk single-crystalline metal halides, very little is known about the photophysics of metal halides in the form of uniform, size-tunable nanocrystals. Here we report low-threshold amplified spont...
