## Description

- description: "Narrow-band emitting phosphors are required to improve performance
    of phosphor-converted light-emitting diodes. Here, we found a new narrow-band
    emitting phosphor Na2Cs2Sr(B9O15)2:Eu2+ using the local structure similarity with
    a known narrow-band emitting phosphor. In a 2D scatter plot of the structure dissimilarity
    between the local structures, Sr site in Na2Cs2Sr(B9O15)2 was located near the
    Ba site of the known narrow-band emitting sulfate phosphor BaSO4:Eu2+ with a distorted
    local structure. We synthesized Na2Cs2Sr(B9O15)2:Eu2+ and characterized the luminescence
    properties by microspectroscopy. Na2Cs2Sr(B9O15)2:Eu2+ has a violet luminescence
    peaked at approximately 417 nm and the narrow full width at half maximum is narrow
    as 26 nm (1497 cm-1).\r\n\r\nThis document is the unedited Author's version of
    a Submitted Work that was subsequently accepted for publication in The Journal
    of Physical Chemistry Letters, copyright © 2022 American Chemical Society after
    peer review. To access the final edited and published work see https://doi.org/10.1021/acs.jpclett.2c02889."
