Abstract

Bu çalışmada, ardışık iyonik tabaka adsorpsiyon ve reaksiyon (SILAR) yöntemi ile oda sıcaklığında sentezlenen ve 550 oC'de H2S gazında 1 saat tavlanan Mo-katkılı ZnS nanoparçacıklarının (NP'ler) yapısal özellikleri incelenmiştir. XRD sonucu, ZnS ve Mo Katkılı ZnS NP'lerin kafes kübik yapıda olduğunu göstermektedir. NP'lerin ortalama kristal boyutu, Debye-Scherrer formülü kullanılarak hesaplandı. Saf ZnS NP'lerin kristal boyutu, doping ile değişti. ZnS ve Modifiye ZnS NP'lerin ortalama kristal boyutu sırasıyla 5.5 nm ve 4.3 nm olarak bulundu.

INVESTIGATION OF STRUCTURAL PROPERTIES OF ZnS AND Mo-DOPED ZnS NANOPARTİCLES ANNEALED IN H2S MEDIUM

Abstract

In this study, the structural properties of Mo-doped ZnS nanoparticles (NPs), which were synthesized at room temperature using the successive ionic layer adsorption and reaction (SILAR) method and annealed in H2S gas for 1 hour at 550 oC, were investigated. The XRD result shows that ZnS and Mo Doped ZnS NPs are in lattice cubic structure. The average crystal size of NPs was calculated using the Debye − Scherrer formula. The crystal size of the pure ZnS NPs varied with doping. The average crystalline size of ZnS and Mo- doped ZnS NPs were found as 5.5nm nd 4.3 nm, respectively.
