Effect of Boric Acid Content on the Structural and Optical Properties of MnS Films Prepared by Spray Pyrolysis Technique

OpenAlex İngilizce

Boron doped MnS lms were obtained by the spray pyrolysis method using the boric acid (H3BO3) as dopant source at a substrate temperature of 350• C. The spray pyrolysis method has a wide range of application areas with a low cost well-suited for the manufacture of solar cells.The properties of boron doped MnS lms were investigated as a function of doping concentration.The X-ray analysis showed that the lms were polycrystalline tting well with a hexagonal structure and have preferred orientation in the [002] direction.The optical band gap of the undoped and boron doped MnS lms were found to vary from 3.38 to 3.20 eV.The changes observed in the energy band gap and structural properties of the lms related to the boric acid concentration are discussed in detail.
