    engineering for enhanced photoluminescence

## Description

- description: With the simple reactants of RE(NO3)3, Na2CO3 and (NH4)2SO4 for hydrothermal
    reaction, dispersed monospheres and nanoplates were selectively synthesized for
    the recently discovered RE2(OH)2CO3SO4.nH2O (RE = Gd0.95Eu0.05, REOCSH) layered
    compound precursor, from which RE2O2SO4 phosphors mostly retaining their precursor
    morphologies were facilely derived via calcination in air at 800 oC, without involving
    SOx. Solution pH was found to decisively determine the chemical composition and
    crystallization kinetics of the initial precipitate, and the possible mechanisms
    of phase/morphology evolution during hydrothermal treatment were proposed by comparatively
    investigating the temperature-course and time-course of REOCSH formation under
    the typical pH values of 6 and 7. It was revealed that (Gd0.95Eu0.05)2O2SO4 monospheres
    emit 1.35 times as strong as nanoplates and may retain as high as 81% of the room-temperature
    intensity at 150 oC. The phosphor monospheres were also analyzed to have a fluorescence
    lifetime of 1.32 ms at room temperature and an activation energy of 0.19 eV for
    the thermal quenching of luminescence.
