Effect of CrF₃ Addition on Photoluminescence Properties of Lead-Free Cs₄SnBr_6-xF_x Zero-Dimensional Perovskite.

ABSTRACT: Zero-dimensional (0D) tin halide perovskites, characterized by their broadband and adjustable emissions, high photoluminescence quantum yield, and absence of self-absorption, are crucial for the fabrication of high-efficiency optoelectronic devices, such as LEDs, solar cells, and sensors. Despite these attributes, boosting their emission efficiency and stability poses a significant challenge. In this work, Cr³⁺-doped Cs₄SnBr_6-xF_x perovskites were synthesized using a water-assisted wet ball-milling method. The effect of CrF₃ addition on photoluminescence properties of Cs₄SnBr_6-xF_x Perovskites was investigated. We found that Cr³⁺-doped Cs₄SnBr_6-xF_x Perovskites e
