## Abstract Bodyβcenteredβtetragonal (BCT) ZnS nanocrystals have been synthesized, for the first time to the best of our knowledge, by using the chemical coprecipitation method at higher synthesis temperatures of 65 and 95βΒ°C. It is confirmed from Xβray diffraction (XRD) studies that in the highβte
Zinc sulfide semiconductor nanocrystals doped with selected transition metal ions (Mn 2+ , Cu 2+ , and Ni 2+ ) have been synthesized via a solution-based method utilizing low dopant concentrations (0-1%) and employing poly(vinylpyrrolidone) (PVP) as a capping agent. UV/Vis absorbance spectra for all
