Determining the Free-Carrier Fraction in 2D Perovskites using Power Dependent Photoluminescence
Listed in e-cienciaDatos
A study using power-dependent photoluminescence measurements, which allows for a correction of the excitation density and also enables the direct determination of the free carrier fraction x.
Description
We focus on two families of Ruddlesden-Popper perovskites, spanning the full range of free carrier fractions vs excitons. Our approach provides a tool for probing the nature of optically excited states in semiconductors and for investigating spatial variations.
The full dataset consists of dataset: Photoluminescence Time Resolved Power Dependent Measurements of a family of RP perovskite (n=1,2,3,4,5) All the data is collected in different flakes of RP perovskites (n=1,2,3,4,5).The data acquisition was done using custom python code and the analysis is performed using custom python code which can be found in GitHub, github.com/phond-uam/Power_Dependent_Photoluminescence Methodology: For details about sample preparation and methodology consult the related publication.

Perovskite nanocrystal are prepared using two different cations with a hot solution synthesis approach. The power dependent photoluminescence measurements are taken using the combination of a picoquant diode laser (LDH-DC-375) and TSCPC module (Picoharp 300). After the laser light is filtered using a single mode fiber the light is directed towards a home-built microscope using a Nikon CFI S Plan Fluor (60x, 0.7 NA) objective.
The PL is then sent to an avalanche photodiode (MPD) controlled by the TSCPC module.
