Chemical Deposition of Thin Films of Lead Selenide

Abstract

A method has been developed which yields chemically deposited thin films of lead selenide on a glass surface. These are uniform in appearance and electrical resistance [1–4 meg/(0.635 cm)2]. The coating solution is made up of a lead citrate complex and dimethylselenourea with sodium sulfite present as an antioxidant. All of the parameters involved in the coating process were studied, including the pretreatment of the glass surface, and the optimum conditions for the coating reaction are described.
