Electron-Hole Diffusion Lengths Exceeding 1 Micrometer in an Organometal Trihalide Perovskite Absorber

Unrestricted Travel in Solar Cells In the past 2 years, organolead halide perovskites have emerged as a promising class of light-harvesting media in experimental solar cells, bu...

Sequential Cation Exchange in Nanocrystals: Preservation of Crystal Phase and Formation of Metastable Phases

We demonstrate that it is possible to convert CdSe nanocrystals of a given size, shape (either spherical or rod shaped), and crystal structure (either hexagonal wurtzite, i.e., ...

Strongly Fluorescent Quaternary Cu–In–Zn–S Nanocrystals Prepared from Cu_1-<i>x</i>InS₂ Nanocrystals by Partial Cation Exchange

We report a high-yield, low cost synthesis route to colloidal Cu1-xInS2 nanocrystals with a tunable amount of Cu vacancies in the crystal lattice. These are then converted into ...

Synthesis of highly luminescent wurtzite CdSe/CdS giant-shell nanocrystals using a fast continuous injection route

We synthesized CdSe/CdS giant-shell nanocrystals, with a CdSecore diameter between 2.8 nm and 5.5 nm, and a CdS shell thickness of up to 7-8 nm (equivalent to about 20 monolayer...
