    • openAccess   CdSe/CdS/CdTe Core/Barrier/Crown Nanoplatelets: Synthesis, Optoelectronic Properties, and Multiphoton Fluorescence Upconversion 

      Khan, Ali Hossain; Bertrand, Guillaume H. V.; Teitelboim, Ayelet; M, Chandra Sekhar; Polovitsyn, Anatolii; Brescia, Rosaria; Planelles, Josep; Climente, Juan I.; Oron, Dan; Moreels, Iwan American Chemical Society (2020-04-10)
      Colloidal two-dimensional (2D) nanoplatelet heterostructures are particularly interesting as they combine strong confinement of excitons in 2D materials with a wide range of possible semiconductor junctions due to a ...

    • openAccess   Piezoelectric Control of the Exciton Wave Function in Colloidal CdSe/CdS Nanocrystals 

      Segarra, Carlos; Climente, Juan I.; Polovitsyn, Anatolii; Rajadell Viciano, Fernando; Moreels, Iwan; Planelles, Josep American Chemical Society (2016-05-25)
      Using multiband k·p calculations, we show that strain-engineered piezoelectricity is a powerful tool to modulate the electron−hole spatial separation in a wide class of wurtzite CdSe/CdS nanocrystals. The inherent ...

    • openAccess   Role of thermally occupied hole states in room-temperature broadband gain in CdSe/CdS giant-shell nanocrystals 

      Tanghe, Ivo; Llusar, Jordi; Climente, Juan I.; Barker, Alex J.; Paternò, Giuseppe Maria; Scotognella, Francesco; Polovitsyn, Anatolii; Khan, Ali Hossain; hens, zeger; Van Thourhout, Dries; Geiregat, Pieter; Moreels, Iwan Wiley (2022)
      Growing CdSe/CdS nanocrystals from a large CdSe core, and employing a giant CdS shell, a continuous, broadband gain spectrum, covering the spectral range between the CdSe and the CdS band edge, is induced. As revealed by ...

    • openAccess   Synthesis of Air-Stable CdSe/ZnS Core–Shell Nanoplatelets with Tunable Emission Wavelength 

      Polovitsyn, Anatolii; Dang, Zhiya; Movilla, Jose L.; Martín García, Beatriz; Khan, Ali Hossain; Bertrand, Guillaume H. V.; Brescia, Rosaria; Moreels, Iwan American Chemical Society (2017)
      In the past few years, several protocols have been reported on the synthesis of CdSe nanoplatelets with narrow photoluminescence (PL) spectrum, high PL quantum efficiency, and short exciton lifetime. The corresponding ...

    • closedAccess   Synthesis of Anisotropic CdSe/CdS Dot-in-Giant-Rod Nanocrystals with Persistent Blue-Shifted Biexciton Emission 

      Polovitsyn, Anatolii; Khan, Ali Hossain; Angeloni, Ilaria; Grim, Joel Q.; Planelles, Josep; Climente, Juan I. American Chemical Society (2018)
      Anisotropic single-phase wurtzite CdSe/CdS nanocrystals were synthesized by colloidal chemistry, introducing ZnCl2 to increase the shell growth in the radial direction. As a result, dot-in-giant-rod nanocrystals were ...
