Researchers have explored BaZr1-xTixS3 BaZrS3-xSex alloys reduce band gaps, allowing them absorb lower-energy photons. However, the hexagonal structures of BaTiS3 BaZrSe3, along incompatibility Ti or Se atoms in BaZrS3, lead phase separation these alloys. In this work, using EuZrS3 Sr0.7Eu0.3ZrS3 examples, we demonstrate that structure chalcogenide can be tuned by Eu A-site cation. EuZrS3, 4f orbitals contribute valence maximum, thereby raising resulting a narrow bandgap 0.54 eV. Furthermore, structural atomic compatibility Sr1-xEuxZrS3 alloy is designed fine-tune both SrZrS3 EuZrS3. also exhibits typical semiconducting characteristics, making it for potential optoelectronic devices.
