摘要

A remarkable optical and electronic properties of halide double perovskites attracted researchers of all corner of globe. Nevertheless, the instability at ambient condition and toxicity of materials hold ups the commercial use. This study describes a straightforward, low-energy, and scalable solution method using reflux temperature to induce the formation of CsKTiCl6 double perovskite material in anhydrous ethanol as a solvent. This research has been focused on incapacitating the limitations associated with the current CsKTiCl6 synthesis, restraints that hinder industrial scalability. This is a first report of mixed cation at A site of double perovskite of titanium which may open a new direction in a design of perovskite material. The material has excellent crystallinity, high stability and excellent optical properties. CsKTiCl6 material not only as a good photocatalyst for the degradation of Rhodamine B in ethanol medium but also can be used for latent fingerprint analysis in the field of forensic science. In summary, our study represents an important step forward in the efficient and cost-effective synthesis of CsKTiCl6 double perovskite material offering a compelling solution for the development of eco-friendly, earth-abundant Pb-free perovskite materials.
