Expanding the Spectral Responsivity of Photodetectors via the Integration of CdSe/ZnS Quantum Dots and MEH−PPV Polymer Composite

Year: 2024

Type: article

Abstract: This study investigates the energy transfer mechanism between the organic polymer poly(2-methoxy-5(2'-ethyl)heroxyphenylenevinylene) (MEH-PPV) and CdSe/ZnS core-shell quantum dots (CdSe/ZnS CSQDs). Additionally, a hybrid ZnO-based photodetector (PD) is fabricated using the composite of MEH-PPV and CdSe/ZnS CSQDs, aiming to gain deeper insights. The combination of MEH-PPV and CdSe/ZnS CSQDs facilitates a broad spectral response in PDs, spanning from the ultraviolet (UV) to the visible range. In particular, PDs with QDs in the composite demonstrate notably excellent photosensitivity to both ultraviolet (UV) light (365 nm) (~5 fold) and visible light (505 nm) (~3 fold).
