title: A Highly Sensitive Narrowband Nanocomposite Photodetector with Gain.
abstract: A narrowband red-light nanocomposite photodetector with gain is presented based on the polymer and fullerene derivative incorporating inorganic quantum dots. The introduced trap-induced hole injection dramatically improves the specific detectivity by 20-fold. A remarkable achievement is obtained with simultaneously increased linear dynamic range to 110 dB and improved noise equivalent power to 5 pW cm(-2).
