Key Points

Substituting nickel with copper alters the structural and electronic properties of oxyfluorides, enhancing their functionality.
The analysis indicates significant optical shifts across the compositions studied, particularly with varying x values from 0 to 1.
Topochemical fluorination of La2Ni1-xCuxO4 enables the creation of these materials at low temperatures, maintaining structural integrity.
These findings highlight the tunability of materials' properties, suggesting practical uses in electronic and optical devices.

Implication

Synthesis shows structural and electronic changes in ruddlesden-popper oxyfluorides, implying potential applications in materials science.

Abstract

In this contribution we report on the synthesis, structure and optical characterization of Ruddlesden-Popper oxyfluorides La 2 Ni 1-x Cu x O 2.5 F 3 (0 ≤ x ≤ 1) obtained by topochemical low-temperature fluorination of La 2 Ni 1-x Cu x O 4 with polyvinylidene...
