Solution Processed Pentacene-PbSe Quantum Dot Polymeric Nanocomposite for IR Photodetection |
| 초록 |
An organic/inorganic polymeric nanocomposite thin film device, consisting of poly-N-vinyl carbazole as host matrix, lead selenide (PbSe) quantum dots as photosensitizer, and the organic semiconductor pentacene derivatives as a conductivity booster was fabricated. Because of the inherent insolubility of pentacene there have been many difficulties in fabrication of devices in the past. In the presented work we have bypssed these problems through the use of easily soluble pentacene precursor or TIPS pentacene. The device exhibits dramatic enhancement of infrared photocurrent due to pentacene. Efficient photogeneration of carriers coupled with enhanced conductance results in high photoconductive quantum efficiency. |
