A facile synthesis of Au-nanoparticles decorated PbI₂ single crystalline nanosheets for optoelectronic device applications.

ABSTRACT: This research communication presents a rapid and facile microwave-assisted synthesis of single crystalline nanosheets (SCNSs) of hexagonal lead iodide (PbI₂) decorated with Au nanoparticles, a potential optoelectronics material. Homogeneous low dimensional AuNP decoration in PbI₂ resulted in a new absorption band at ~604 nm and a shift in band gap from 3.23 to 3.00 eV. The significant enhancement of photoluminescent (PL) intensity observed in the AuNP-PbI₂ SCNSs is attributed to the coupling of the localized surface plasmon resonanzce of AuNP leading to improved excitation and emission rates of PbI₂-SCNSs in the region of the localized electromagnetic field. The Au-PbI₂ SCNSs display a compelling increment in photoconductivity, and its
