IPOP 3.0: Optical Properties of 3,952 Inorganic Phosphor Compositions

The IPOP dataset version 3.0 is a collection of experimentally validated inorganic phosphors and their optical properties sourced from 553 scientific articles. It contains 3,952 combinations of 21 dopant elements in 2,238 host materials. The dataset was constructed by Seunghun Jang and includes features such as emission wavelengths, quantum efficiency, and chromaticity coordinates.

Use Cases

• Predicting photoluminescence emission maxima based on host and dopant compositions.
• Analyzing the relationship between dopant concentration and quantum efficiency for phosphor optimization.
• Screening host materials for specific CIE chromaticity coordinates for display applications.
• Modeling thermal quenching behavior to assess phosphor stability.
• Identifying outlier data points using the provided Local Outlier Factor (LOF) scores for data quality control.

Strengths

• Contains 3,952 data points from 553 peer-reviewed articles, suggesting a substantial literature review.
• Includes 52 engineered features derived from atomic properties, which may aid machine learning tasks.
• Dataset has undergone multiple versioned updates with specific quality improvements, such as duplicate removal and outlier scoring.

Limitations

• Row count and file size are unknown, which may limit suitability assessment for large-scale processing.
• Column-level documentation is absent from the provided metadata; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
