Non-radiative processes in metal halide perovskite semiconductors probed by photoluminescence microscopy
(2018) 13th International Conference on Hole Burning, Single Molecule, and Related Spectroscopies: Science and Applications, HBSM 2018 In EPJ Web of Conferences 190.- Abstract
Organo metal halide perovskites are solution processed semiconductors that recently attracted a great attention. They possess a rather "soft" and (photo) chemically active solid structure allowing for ion migration and other mass diffusion processes. This is a likely reason why non-radiative recombination centres in these materials are activated and deactivated on relatively slow time-scales. This dynamics reveals as photoluminescence (PL) fluctuations (blinking) of individual microcrystals and local areas of films and allows for application of a broad range of single molecule spectroscopy methods including optical super-resolution. Studying PL blinking resolves properties of individual non-radiative centres and helps to unravel their... (More)

Studying PL blinking resolves properties of individual non-radiative centres and helps to unravel their chemical nature.
