Temporal coherence of single photons emitted by hexagonal Boron Nitride defects at room te

Experimental data from a study on the temporal coherence of single photons emitted by color centers in hexagonal boron nitride. The dataset includes photoluminescence spectra, time-resolved fluorescence decay, second-order correlation measurements, and Michelson interferometry data for several emitters under different excitation conditions. It was created by Vidal Martínez-Pons, Juan Vicente and last updated on 2025-12-21.

Use Cases

• Analyzing phonon dephasing processes based on Michelson interferometry fringe visibility data.
• Characterizing single-photon emission properties based on second-order correlation function measurements.
• Studying the impact of excitation conditions on emitter coherence based on photoluminescence spectra under different laser wavelengths.
• Evaluating the electron-phonon coupling strength at room temperature based on coherence time and Debye-Waller factor data.

Strengths

• Data is organized into four main experimental categories with subfolders, suggesting a clear structure.
• Includes data from multiple hBN emitters and under varied excitation conditions, allowing for comparative analysis.
• Dataset was used to generate figures for a peer-reviewed publication, indicating it has been validated for research.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file sizes are unknown, which may limit suitability assessment.
• The description notes a strong electron-phonon coupling at room temperature, suggesting data may be limited for quantum applications without cryogenic conditions.
