چکیده انگلیسی
In this study, pure and transition-metal (silver (Ag)) activated zinc sulfide (ZnS) nanoparticles were prepared using a hydrothermal technique. The particles have spherical shape. The average crystallite size value of ZnS:Ag nanoparticles estimated from the XRD patterns is 4.2â¯nm. Our results also show that the prepared ZnS has a zinc blende structure. An absorption peak at 350â¯nm was observed from UV-Vis spectrum for 0.05â¯mol% Ag doped ZnS which is related to the cubic phase of bulk ZnS. A typical Raman peak of ZnS:Ag crystal at around 346â¯cmâ1 is detected. An optimum activating level of Ag for improved photoluminescence (PL) property is found by measuring the fluorescence of samples. The PL spectra of ZnS:Ag nanoparticles showed a new PL band at 473â¯nm. Results of ZnS:Ag nanoparticles preparation and optimization, along with structural and optical estimation are discussed and addressed thoroughly. A linear relationship between PMT counts and the flounces of alpha particles has been achieved. The detection efficiency of Lucas cell coated with the prepared samples has been determined.
