OH- Effect on the Growth and Structural Properties of Chemical Bath Deposited ZnS Quantum Thin Films

摘要

Zinc sulfide (ZnS) quantum thin films have been deposited from precursors with a variety of OH concentration onto microscope glass substrates by chemical bath deposition method. The growth and structural properties have been investigated. XRD patterns of ZnS films obtained from acidic solution showed a favorable wurtzite structure, while for those obtained from alkaline solution, showed a sphalerite structure. The growth studied of the deposited films has also shown that the OH" played a vital role in nucleation and the film growth.
