| Popis: | Photosensors based on quantum dot and star like PbS has been successfully fabricated. Lead sulfides were synthesized by sonochemical and hydrothermal methods and coated on Cu interdigitated electrodes. The current-voltage (I–V) characteristics show linear and exponential behavior for quantum dots and star like PbS respectively. The photosensitivity is high for fabricated detectors by star like PbS. However, fast response time was observed for the detector fabricated by quantum dots. |
