Power-dependent photoluminescence measurements on two families of Ruddlesden-Popper perovskites (n=1-5) enable direct determination of the free carrier fraction versus excitons. The dataset, collected using a picoquant diode laser and time-correlated single photon counting module, provides a tool for probing optically excited states in semiconductors. Author Ferry Prins published the data via e-cienciaDatos Harvested Dataverse in April 2026.
Use Cases
- Modeling free-carrier versus exciton fractions in 2D perovskites based on power-dependent photoluminescence data.
- Investigating spatial variations in optically excited states within semiconductor flakes as described in the methodology.
- Benchmarking analysis methods for power-dependent photoluminescence using the provided custom Python code.
- Comparing carrier dynamics across different Ruddlesden-Popper perovskite families (n=1 to n=5).
Strengths
- Focuses on two distinct families of Ruddlesden-Popper perovskites, spanning the full range of free carrier fractions.
- Methodology details specific equipment: a picoquant diode laser (LDH-DC-375) and a TSCPC module (Picoharp 300).
- Custom Python code for data acquisition and analysis is publicly available on GitHub, facilitating reproducibility.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count and dataset size are unknown, which may limit suitability assessment.
- Description metadata is limited; actual data quality requires manual inspection after download.
