## Description

- description: Ni2+-doped LaAlO3 perovskite ceramic samples with a charge compensator
    (M4+) were prepared and their luminescent properties were investigated. The LaAlO3:Ni2+–M4+
    (M = Sn, Hf, Ti, Zr) perovskites show a broad near-infrared (NIR) luminescence
    peaking at around 1070 nm with 150 nm fwhm due to the Ni2+:3T2-3A2 transition.
    The Sn4+-codoped one showed the highest NIR luminescence intensity. The valence
    state of major Ni ions is changed from Ni3+ to Ni2+ by codoping with Sn4+ based
    on X-ray absorption spectroscopy. The LaAlO3:Ni2+–Sn4+ shows the shortest luminescence
    peak wavelength (λem = 1070 nm) at 300 K due to the strong crystal field and also
    shows the highest quenching temperature, T50% of 608 K in the temperature dependence
    of PL intensity, due to the largest activation energy among the Ni2+-doped NIR
    phosphors ever reported. Based on the positive trend in the plot of T50% vs PL
    peak energy, it is concluded that the dominant quenching process in almost all
    Ni2+ phosphors is the thermally activated crossover process. It is also demonstrated
    that the luminescence peak wavelength is shifted from 1070 to 1235 nm continuously
    by substituting Ga ions for the Al site.
