Photoemission and Energy Gap of CdS Synthesized by Solid State Microwave-Plasma

Abstract:

Article Preview

Purified cadmium sulfide crystals were successfully synthesized from 1:2 molar ratio of Cd and S powders by a 900 W microwave plasma for 120 min and 140 min. In the present research, XRD and SAED patterns including SEM, TEM, and FIB images were used to indicate phase and morphology of the products, with their Raman peaks at 303 and 605 cm-1. Photoemission was determined to be 537 nm, and direct energy gap (Eg) to be 2.48-2.51 eV.
