Continuous-wave Lasing in a Solid Polymer
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 کاملRoom temperature continuous–wave green lasing from an InGaN microdisk on silicon
Optically pumped green lasing with an ultra low threshold has been achieved using an InGaN/GaN based micro-disk with an undercut structure on silicon substrates. The micro-disks with a diameter of around 1 μm were fabricated by means of a combination of a cost-effective silica micro-sphere approach, dry-etching and subsequent chemical etching. The combination of these techniques both minimises ...
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...
متن کاملLow-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 کاملPhotostability of 2D Organic-Inorganic Hybrid Perovskites
We analyze the behavior of a series of newly synthesized (R-NH₃)₂PbX₄ perovskites and, in particular, discuss the possible reasons which cause their degradation under UV illumination. Experimental results show that the degradation process depends a lot on their molecular components: not only the inorganic part, but also the chemical structure of the organic moieties play an important role in bl...
