## Description

- description: "Phosphors that exhibit tunable broadband emissions are highly desired
    in multi-functional LEDs, including pc-WLEDs and pc-NIR LEDs. In this work, broadband
    emissions were obtained and modulated in the unexpectedly wide spectral range
    of 517-609 nm for (Lu0.99-xGdxBi0.01)2WO6 phosphors via tuning the Gd3+ content
    (x = 0-0.99). The effects of Gd3+ doping on phase constituent, particle morphology,
    crystal structure, and photoluminescence were systematically investigated. Broadband
    green emission was obtained with the Gd3+-free (Lu0.99Bi0.01)2WO6 phosphor (x
    = 0), whose emission intensity was enhanced by 50% \r\nwith 5 at% of Gd3+ (x =
    0.05). Phase transition happened when x ＞ 0.50, and broadband red-NIR emission
    was obtained when x = 0.75-0.99. Three luminescence centers were proved to be
    responsible for the broadband emissions via crystal structure, spectral fitting
    and fluorescence decay analysis. A pc-WLED with high color rendering index (Ra
    = 91.3), stable emission color, and low color temperature (3951 K) was fabricated
    from the (Lu0.94Gd0.05Bi0.01)2WO6 broadband green phosphor, and an LED device
    that simultaneously emits high color rendering white light and NIR light was obtained
    with the (Gd0.99Bi0.01)2WO6 broadband red-NIR phosphor. Night version and noninvasive
    imaging were also demonstrated for the latter LED device."
