Аннотация
The possibility of using semiconductor nanocrystals in photodetectors for optical detection of open flame has been explored. The spectral range boundaries of response of flame detectors have been concretized. In accordance with this, colloidal lead sulfide nanocrystals absorbing in the range of 1–1.5 μm have been synthesized. Photoresistors with different ligand compositions have been made from these particles. For the obtained samples, the current–voltage characteristics were measured and the photosensitivity and specific
detectivity parameters were calculated. A theoretical estimate of the flame detection range has been made for the samples. It has been shown that a photosignal can be reliably detected at a distance of more than 80 m.
