High Responsivity Fire Detectors Based on PbS Colloidal Quantum Dot Photoconductors
IEEE Photonics Technology Letters(2017)
摘要
In this letter, we report on high responsivity fire detectors based on PbS colloidal quantum dots photoconductors. The devices operate in the near infrared and are equipped with a visible light silicon filter for wavelength selectivity. Devices are fabricated by a simple, low cost, and silicon compatible process based on drop casting of a ligand exchanged solution of PbS nanoparticles. The photode...
