    Abstract:

    In this work we utilise luminescent properties of Mn4+ doped Li4Ti5O12 - a very promising material for ultrafast-charge-discharge and long-cycle-life batteries [1]. Applying lifetime-based luminescence thermometry on Mn4+ doped materials the remote and non-contact temperature readings are possible with great relative sensitivity [2-4].
    The Mn4+ doped Li4Ti5O12 samples were prepared by the one step solid-state method using stoichiometric amounts of Li2CO3, TiO2 and MnO2 at 850 oC to obtain cubic spinel structure with space group Fd-3m as confirmed by X-ray diffraction analysis. In this host, Mn4+ is in a strong crystal field providing the strong absorption around 500 nm due to 4A2g →4T2g electric spin-allowed electron transition and with emission around 679 nm on account of 2Eg →4A2g spin forbidden electron transition. Due to the coupling to phonon modes of the host material [5] the change of radiative decay rate (radiative lifetime) starts at very low temperatures (»75 K). In addition, the low value of energy of 4T2g level (20000 cm−1) leads to the strong emission and radiative lifetime quenching starting at low temperatures (»250 K) which favours the use of this material for the luminescence thermometry in a broad temperature range.
    Temperature dependences of photo-luminescent emission spectra and emission decay are measured over the 10–350 K range exhibiting quite large value of relative sensitivity (2.6% K−1@330 K) that facilitates temperature measurements with temperature resolution better than 0.15 K around room temperature.
