| Abstract |
Fluorescent materials have been attracting attention due to their diverse applications. In this study, we synthesized Mn4+-doped Li2TiO3 and characterized its luminescent property. The fluorescence emission was the most intensive when the Mn4+ ion content was 1% and the synthesis temperature was 800℃. According to XRD analysis, the cation distribution are changed with the synthetic temperature, which affects the fluorescence emission in the lattice. The Li2TiO3:Mn4+powder were dispersed in toluene using dioctyl sulfosuccinate as a surfactant. The dispersion colloidal was charaterized with a laser scattering particle-size analyzer and scanning electron microscope. On the basis of mixing with the Li2TiO3:Mn4+ colloidal dispersion and polydimethylsiloxane, The fluorescent film was successfully fabricated.
