Bandgap engineering of colloidal zinc oxysulfide via lattice substitution with sulfur.

Zinc oxysulfide nanocrystals with zinc blende phase are synthesized through a wet-chemical method. An affirmation of the crystal structure, elemental homogeneity and phase transformation is obtained by X-ray diffraction and authenticated by electron micrographic studies. Theoretical observations have strongly supported the thermodynamic solubility limit for its (30%) formation.

Low-temperature synthesis of quantum size gadolinium monosulfide (GdS) nanoparticles and their pathogen capture efficiency.

Synthesis of paramagnetic gadolinium monosulfide nanoparticles at low temperature is achieved using dextrose ligands.
