  Recently, low-dimensional organic-inorganic hybrid halide compounds have
aroused great attention in the optoelectronic field, due to the unique topology
and optical properties. Herein, we report an Mn4+ doped [N(CH3)4]2TiF6
zero-dimensional organic-inorganic hybrid phosphor, which could not only
exhibit very narrow and pure red emission, but also maintain efficient emission
intensity at room temperature. The crystal structure, photoluminescence
properties and temperature sensing application are discussed. The excellent
temperature dependent luminescent properties are attributed to the rigid
structure and isolated MnF62- octahedra in the total crystal framework. These
results will help design suitable materials and devices in both warm white
light emitting diodes and optical sensors.
