## Description

- description: "Novel La1-xBaxAl1-xTixO3:0.001Mn4+ (LBAT:0.001Mn4+, x=0-0.2) and La1-yYyAl1-yGayO3:0.001Mn4+
    (LYAG:0.001Mn4+, y=0-0.2) samples were successfully synthesized through a high-temperature
    solid-state reaction, and tunable ZPL of Mn4+ was found by cationic pair substitution
    of Ba2+-Ti4+ and Y3+-Ga3+ for \r\nLa3+-Al3+ in LaAlO3:Mn4+. The ZPL intensity
    is related to the local symmetry around Mn4+ and the ZPL energy corresponds to
    the Mn-O bond distance and the O-Mn-O bond distortion. Through co-doping Ba2+-Ti4+,
    the ZPL at 710 nm is enhanced and the intensity increases continuously with increasing
    the x value, due to the local symmetric degree of Mn4+ decreases slowly. However,
    the Y3+-Ga3+ co-doping induces linear and quick increase of the intensity of ZPL
    at 704 nm with increasing y value, due to the local symmetric degree of Mn4+ decreases
    quickly. The octahedral tilting distortion is very important for the local symmetry.
    Ba2+-Ti4+ co-doping reduces octahedral tilting distortion, but Y3+-Ga3+ co-doping
    induces a serious \r\noctahedral tilting distortion. Consequently, the ZPL emission
    exhibits an octahedral-tilting dependent behavior. Mainly due to the larger distortion
    of O-Mn-O bond, the energy of ZPL for LYAG:0.001Mn4+ is higher than that for LBAT:0.001Mn4+.
    The outcomes of this work provide a promising way to regulate \r\nthe ZPL intensity
    and energy by tuning the local structure around Mn4+, and they may have wide implication
    for Mn4+-doped phosphors and solid state lighting."
