摘要
Hexagonal rare-earth manganites have attracted considerable interest due to their complex multiferroic properties,and they possess a spontaneous electric polarization and may be utilized in various technological applications ranging from solar cells to non-volatile memories and light polarizers.The narrow bandgap of hexagonal rare-earth manganite-based compounds can perform remarkable optical anisotropy properties,which make these very efficient photovoltaic materials in parallel with the widely used TiO_(2)-based materials.Substantial enlargement of the traditional field of hexagonal rare-earth manganite photocatalysis also arose in the last decade.This article imparts an extensive review of the rational synthesis,optical properties,structural characterization,and applications of hexagonal rare-earth manganite.Fundamental properties of hexagonal rare-earth perovskite manganite are also emphasized,and a range of unique applications in photocatalysis and photovoltaics are discussed.Eventually,we wind up this review with some linear perspectives and future research in this area.
