Ba2LiAlSi2O8:Eu2+ Phosphor Crystal Structure Data for LED Applications

A Crystallographic Information File (CIF) dataset details the crystal structure of a new blue-green emitting phosphor, Ba2LiAlSi2O8:Eu2+. The data was produced by Akihiro Nakanishi and published on figshare in May 2026. It includes single-crystal X-ray diffraction results and density functional theory calculations supporting the material's structure.

Use Cases

• Modeling luminescence properties based on the provided crystal structure and lattice parameters.
• Developing new LED phosphors to fill the cyan gap in white LEDs, as mentioned in the description.
• Validating computational chemistry models using the provided density functional theory calculation results.
• Fabricating prototype PC-LEDs using the phosphor's CIE chromaticity coordinates and excitation/emission peak data.

Strengths

• Includes specific crystallographic data: space group Pna2₁ (No. 33) with lattice parameters a=8.04521(11) Å, b=19.0484(2) Å, c=5.02228(6) Å.
• Reports performance metrics for the phosphor: luminescence peak at 497 nm, full width at half-maximum of 85 nm, internal quantum efficiency of 51.0%, and external quantum efficiency of 42.7%.
• Describes the synthesis method (solid-state reaction) and characterization approach (single-particle diagnosis).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is small (1.9 MB), which may indicate limited scope.
