Effect of temperature and time on the structural properties of PbS nanofilms

Abstract

In this research, lead acetate as a source of Pb 2+ and thiourea as a source of S 2 have been used, and the e ects of deposition time (tD < 90 min) and deposition temperature (T D : 28, 55 C) on the prepared thin lms of Lead-Sul de have been investigated. In order to investigate the morphology of thin lms and crystalline nanostructure of the lms, atomic force microscopy and X-ray di raction have been utilized, respectively. Values of lattice constant for prepared PbS lms vary in the range of 0.5937-0.5959 nm. Preferred growth orientation for prepared lms is 200. The thickening process of layers has declined after 60 min (t at 28 C: 130-530 nm and t at 55 C: 300-975 nm).

Facile Production Method of PbS Nanoparticles via Mechanical Milling of Galena Ore

“…Most of nanomaterials’ applications in this field are in the form of thin films. This subject has been well covered by many workers in this advanced field, to investigate the synthesis methods and applications of nano-lead sulfide compounds [ 8 , 9 , 10 , 11 , 12 ].…”
