Effect of film forming quality on the performance of PbSe detector

Abstract
The response band of lead selenide is 1 to 5 um. There are high response rates and sensitivity for lead selenide at room temperature. Chemical bath deposition is a common method for the synthesis of thin films. Due to the complexity of thin films prepared by chemical bath deposition, the consistency of thin films prepared at present is poor, it is difficult to prepare large area arrays. The stability constant K of the complex is crucial for film formation. K is mainly related to the concentration of hydroxide. By optimizing the molar amount of each initial solute, the relationship between the molar amount and the film forming mass was studied. The controllability of particle size and the uniformity of the film are further realized by controlling the molar, temperature and PH. It plays an important role in the preparation of infrared photoconductive units and array detectors.
