## Title

    GAP:Mn4+ transparent ceramic film
  title_type: original

## Description

- description: 'We developed a pressureless sintering method to prepare GdAlO3: Mn
    (GAP: Mn) transparent ceramic films, which were prepared by spin coating layered
    rare earth hydroxide (LRH) on amorphous alumina substrate and sintering at 1550
    oC for 2 hours. Through the interface reaction, the Al2O3 reacted with Gd2O3 to
    form mesophase Gd4Al2O9 below 1550oC. However, the final products are GdAlO3 at
    1550 oC. The GAP: Mn4+ film exhibits a high transmittance of about 90%. Under
    UV excitation at 310 nm, the ceramic film outputs deep red and NIR emissions,
    which are both arising from the 2Eg-4A2g transition of Mn4+. Due to the electron
    traps arising from unequal valence substitution, the ceramic film exhibits a negative
    thermal quenching phenomenon. The ceramic film has a good luminescence thermal
    stability, because its emission intensity at 150 oC maintains over 72% that at
    room temperature. This work may pave a new way to fabricate transparent ceramics
    using layered rare earth hydroxides. '
