چکیده انگلیسی
High quality poly crystalline nanostructured PbS thin film has been deposited on a glass substrate by chemical deposition technique. The hydrazine hydrate as a reducing agent for lead ion has been used for preparation of the film. After deposition, the film has been annealed, and then the influence of hydrazine hydrate on the dark resistivity and photosensitivity of film have been investigated. It was found that in the presence of hydrazine hydrate in chemical deposition bath, the resistance of the prepared film increases to mega ohm. The measured room temperature detectivity of the film is 4 Ã 109 Wâ1 Hz1/2 cm at the wavelength of 2.4 μm. The experimental results have shown that the PbS film, which has been prepared according to this procedure, can be applied as an infrared detector in the range of 1.0-3.0 μm.
