Yttrium doped ZnS samples Zn{sub 1-x}Y{sub x}S with nominal compositions (x = 0.00, 0.04 and 0.06) were synthesized by a chemical co - precipitation route at room temperature. The synthesized Zn{sub 1-x}Y{sub x}S nanoparticles were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and UV–VIS spectrometer. XRD patterns revealed that entire peaks corresponding to the various planes of cubic zinc blend structure with no segregation of Y. The lattice parameters were calculated for the Y doped ZnS using XRD data and it found to be slightly smaller than pure ZnS, which indicate substitution of Y in to ZnS lattice. The average crystallite size was calculated using Debye - Scherrer’s formula for pure and Y doped ZnS samples. It is observed that grain size is in the range 30 to 12 nm. Band gap of Y doped ZnS nanoparticles has been calculated using UV-Vis spectrometer. It is found that the band gap decreases as content of Y increases, It may be due the smaller average grain size or ionic radii. The functional groups and chemical interactions of Y substituted Zinc sulfide samples were detected peaks using FTIR spectra and observed the presence of functional groups in the samples. It outlines the formation of ZnS with the stretching vibrational mode around at 511 cm{sup −1}. It is evidently confirmed from FTIR spectra that yttrium substitutes into ZnS lattice.
