(NH₄)₂AgX₃ (X = Br, I): 1D Silver Halides with Broadband White Light Emission and Improved Stability.

ABSTRACT: Recently, ternary copper(I) halides have emerged as alternatives to lead halide perovskites for light emission applications. Despite their high-efficiency photoluminescence (PL) properties, most copper(I) halides are blue emitters with unusually poor tunability of their PL properties. Here, we report the impact of substitution of copper with silver in the high-efficiency blue-emitting Cu(I) halides through hydrothermal synthesis and characterization of (NH₄)₂AgX₃ (X = Br, I). (NH₄)₂AgX₃ are found to exhibit contrasting light emission properties compared to the blue-emitting Cu(I) analogues. Thus, (NH₄)₂AgBr₃ and (NH₄)₂AgI₃ exhibit broadband whitish light emiss
