Optical Property dataset of Inorganic Phosphor (IPOP dataset ver 3.0)

We constructed a high-quality and reliable dataset that contains experimentally validated inorganic phosphors and their optical properties sourced from the literature on inorganic phosphors. Since the IPOP dataset ver 1.0 announcement on December 22, 2022, IPOP dataset ver 3.0 has been published through a continuous dataset update process. The updated details for the dataset are as follows.1. Data on papers cited less than ten times were deleted in the IPOP dataset.2. Additional data on Eu-doped phosphors have been added.3. The second and third maxima information for PLE data has been added.4. Alkali metals were treated as hosts rather than dopants.5. PLE detection energy was renamed to Monitoring energy.6. Duplicate data has been deleted.7. Inorganic Crystal Structure Database (ICSD) ID information has been added.8. LocalOutlierFactor (LOF) score information has been added.IPOP dataset ver3.0 includes 3,952 combinations of 21 dopant elements in 2,238 host materials from 553 articles.1 Tag — The numbering of data points2 Inorganic phosphor — Composition of phosphor3 Host — Host composition of phosphor4 1st dopant — 1st dopant atom of phosphor5 1st dopant valency — Valency of 1st dopant atom6 1st dopant concentration — Doping concentration of 1st dopant7 2nd dopant — 2nd dopant atom of phosphor8 2nd dopant valency — Valency of 2nd dopant atom9 2nd dopant concentration — Doping concentration of 2nd dopant10 Temp.
