Electrical and optical characteristics of Ni doped ZnS clusters

A simple. easy approach to the synthesis of nickel (Ni) doped zinc sulphide (ZnS) clusters is reported. The synthesis of Ni-ZnS clusters involved mixing and drying of zinc acetate, sodium sulphide and acrylic acid in appropriate ratio and adding Ni at proper conditions. These clusters were trapped in polyacrylic acid (PAA) to form a PAA capping to provide stability. The clusters were characterized using high resolution SEM for morphological investigation; XRD for its crystalline nature: photoluminescence (PL) for optical characterization and electrical conductivity measurement. Clusters of Ni-ZnS were formed of the size -10 nm. (c) 2009 Elsevier B.V. All rights reserved.
