The growth of ZnS films from ammonia solutions using thiourea as a sulfur precursor has been investigated. In situ growth kinetic studies have been performed by means of the quartz crystal microbalance (QCM) technique. The experiments have been carried out in pH buffered conditions (pH≈11) and the effect of the addition of amines has been investigated. The film are characterized by various techniques (Optical, Rutherford Back Scattering, Transmission Electron Microscopy). The composition of zinc hydroxosulfide is ranging between almost pure ZnS to mainly Zn(OH)2 depending on the deposition conditions.
