| Abstract: | Lead selenide thin film for shortwave infrared detector is deposited on quartz glass substrate by chemical bath deposition.XRD,SEM,TEM and Fourier transform infrared spectroscopy are employed to characterize PbSe thin films.Experiments show that the film is polycrystalline nano structure,with grain size about 10 nm.Absorption edge of the film shifts to 1.6 μm due to quantum confinement effect.Proto-type PbSe photoconductive detector is fabricated.The responsive range is 0.6 to 1.5μm in spectral test under ambient temperature. |

| Keywords: | lead selenide chemical bath deposition photoconductive detector spectral response |
