Rinku Saran, Muhammad N. Nordin and Richard J. Curry Facile Fabrication of PbS Nanocrystal:C60 Fullerite Broadband Photodetectors with High Detectivity Advanced Functional Materials 23
PbS nanocrystal/C60 fullerite photodetectors exhibiting broadband UV-vis-near IR response with high detectivity are demonstrated using a simple one-step deposition process. The devices operate without the need of a transparent conducting substrate under ambient air conditions exhibiting a fast photocurrent rise time and a biexponential microsecond decay. These devices offer an attractive low-cost solution for large-area broadband photodetectors.
