Hybrid organic-inorganic chiral perovskites are considered criticalcandidates as alternative active layers owing to their superior optoelectronicproperties such as circulary polarized light (CPL) detection and effectivelight absorption. Chiral plasmonic effect is expected to dramatically enhancethe chiroptical properties of perovskites via enhanced chiral near-field. Inthis work, we aim to develop unprecedented chiral perovskite photodetectorsusing the [(R, S)-MBA]2PbI4 perovskites combined with Aunanoparticles stabilized by cysteine ligands (L, D-cys AuNP). We show that the integrationof cys-AuNP into the active layer improved CPL detection capabilities and lightabsorption due to the plasmonic effect. The established synergy between the twocomponents may open the pathway to greatly improve the chiroptical deviceperformance. |
