Colloidal HgTe nanocrystals with widely tunable narrow band gap energies: from telecommunications to molecular vibrations.
A convenient, aqueous-based synthesis of stable HgTe nanocrystals with widely size-tunable room temperature emission between wavelengths of 1.2 to 3.7 mum is demonstrated. By the choice of the thiols, applied as stabilizers, we optimized the growth dynamics, the luminescence quantum yields (up to 40%), and a ligand-exchange procedure, required to transfer the nanocrystals from water to nonpolar...
متن کاملMultiexciton Generation in IV-VI Nanocrystals: The Role of Carrier Effective Mass, Band Mixing, and Phonon Emission.
We study the role of the effective mass, band mixing, and phonon emission on multiexciton generation in IV-VI nanocrystals. A four-band k · p effective mass model, which allows for an independent variation of these parameters, is adopted to describe the electronic structure of the nanocrystals. Multiexciton generation efficiencies are calculated using a Green's function formalism, providing res...
متن کاملBand-edge excitons in PbSe nanocrystals and nanorods
We investigate the fine structure of band-edge excitons in PbSe nanocrystals and nanorods using circularly polarized magnetophotoluminescence and optically detected magnetic resonance and, based on the results, propose a singlet-triplet model of exciton photoluminescence from nondegenerate conduction and valence bands. From the data and model we extract g-factors for electrons and holes of +1.2...
متن کاملNarrow-Band Biphoton Generation near Atomic Resonance
Generating nonclassical light offers a benchmark tool for the fundamental research and potential applications in quantum optics. Conventionally, it has become a standard technique to produce the nonclassical light through the nonlinear optical processes occurring in nonlinear crystals. In this review we describe using cold atomic-gas media to generate such nonclassical light, especially focusin...
متن کاملEvaluation of Efficacy and Safety of Combination of Narrow Band Ultraviolet B and Topical Calcipotriol Versus Narrow Band UVB alone in the Treatment of Vitiligo
Background: Narrow band Ultraviolet B (NBUVB) has been used successfully for the treatment of vitiligo. Recently, topical calcipotriol has also been used as immunotherapy or as a part of combination therapies. The aim of this study was to compare the clinical efficacy and safety of NBUVB and NBUVB plus topical calcipotriol in the treatment of generalized vitiligo.Methods: NBUVB phototherapy was...
