## Description

- description: A new narrow-band emitting phosphor K2ZnP2O7:Eu2+ was discovered by
    extracting promising crystal structures from a database. Regarding the local structures
    consisting of the central cation and surrounded ligands extracted from the crystal
    structure, we obtained the quantitative dissimilarity between the local structures
    and visualized the data as a 2D scatter plot using the t-SNE method. As a result,
    one of the K-sites of K2ZnP2O7 was located near the reference local structure
    Ba-site of the known narrow-band phosphor BaSi2O2N2:Eu2+ in the scatter plot.
    We synthesized K2ZnP2O7:Eu2+ and measured the luminescence properties. K2ZnP2O7:Eu2+
    showed a narrow-band emission at 440 nm with a full width at half maximum of 30
    nm.
