Influence of Cerium (Ce) Doping on the Optical Properties of Silver Sulphide (Ag2S) and Silver Sulphide (Ce: Ag2S) Thin Films Deposited by Electrodeposition Method

Lois Ugomma Okafor, Donald Okoli & Azubike Josiah Ekpunobi · Journal of Materials Science Research and Reviews · 2024

Thin Films of silver sulphide (Ag2S) have been successfully deposited onto FTO glass substrate using electrodeposition method to investigate the effects of Ce doping on Ag2S films. Silver trioxonitrate (V) and Sodium thiosulphate were the precursors used for silver and sulphur io...
