RGB tri-luminescence in organic-inorganic zirconium halide perovskites.

ABSTRACT: Materials with two or more fluorescence features under different excitation sources have great potential in optical applications, but luminous materials with three emission characteristics have been largely undeveloped. Here, we report a novel zero-dimensional (0D) organic-inorganic hybrid ((C₂H₅)₄N)₂ZrCl₆ perovskite with multiple emissions. The zirconium-based perovskite exhibits a red emission around 620 nm, a green emission at 527 nm, and a blue emission around 500 nm. The red and green emissions come from self-trapped excitons (STEs) and the d-d transitions of Zr(iv), respectively, which are caused by distortion of the [ZrCl₆]^2- octahedra. The blue emission is caused by thermally activated delayed fluorescence
