## Description

- description: This letter reports a b-SiAlON:Eu2+ green phosphor with the composition
    of Eu0.00296Si0.41395Al0.01334O0.0044N0.56528. The phosphor powder exhibits a
    rod-like morphology with the length of ,4 mm and the diameter of ,0.5 mm. It can
    be excited efficiently over a broad spectral range between 280 and 480 nm, and
    has an emission peak at 535 nm with a full width at half maximum of 55 nm. It
    has a superior color chromaticity of x=0.32 and y=0.64. The internal and external
    quantum efficiencies of this phosphor is 70% and 61% at lex=303 nm, respectively.
    This newly developed green phosphor has potential applications in phosphor-converted
    white LEDs.
